• ESXi list of USB devices

  Hi all

  I need to connect USB on ESXi 4.1 drive to VM, but I do not consider the USB device. Perhaps is connected to the other VM, or disk is disabled, but server is located on the remote location and I can't check this.

  Can I list the USB devices connected to the server or the computer virtual ESXi?

  Thanks for the reply

• ESXi 6 - unable to connect the USB device to VM

  Hi people:

  I have a problem with a specific USB 3 device to try to connect to a virtual computer.  The device is a Toshiba USB 3 5 TB hard drive, and it is recognized by ESXi I see when I do a lsusb command, but it is never offered as a choice available to connect to a virtual computer.  I tried to restart management agents, restart ESXi with the connected device so that it is immediately detected at startup.  I tried using the web client to vcenter server appliance and the native client C.  She just never appears as a choice just as if it is not there.  Other USB 3 devices, including a Startech gigabit network device and another 2 TB Toshiba USB drive appear as a choice, so it doesn't seem to be a problem with USB 3 devices as a whole.  I have connected to other computers and even an Arch Linux VM under the same ESXi which has a Startech USB 3 connected via PCI Passthrough controller and it works in all places.  I tried to connect to a USB 2 port just for the heck of it, and I got the same result (invisible to virtual machines) here is what information I have via the newspapers.  I see a few entries on the device being suspended in the vmkernel journal, but I don't know if it is normal for a device until it is assigned to a virtual computer.

  Any ideas what is wrong or how to fix welcome.

  Hi guys, I just had the same issue and it resolved on my test environment.

  I got the device ID using "lsusb".

  Bus 004 Device 002: ID 0480:d011 Toshiba America information. Systems, Inc..

  where 0480:d011 is the device ID

  Then ran the following command:

  oddities s esxcfg-module = 0480:d011:i usb-storage

  After a reboot I was able to cross the device for my VMs.

  I'm not an expert in this field, as far as I can understand of this thread: problem mit USB Passthrough (eine andere nicht, geht HDD) - to vSphere5 / ESXi 5.0 5.1 - VMware Forum und "usb-storage" module crashes when you try to access the drive and does not pass through to the arbitrator of the usb. The person in this thread turns off the usb storage but I boot from USB and so I couldn't do it. Steal the idea of this thread: zero calorie tech deals: VMFS formatted USB sticks in VMware vSphere 5.1 I could exclude the USB from the usb-storage module device (I think).

  I have not tested how this affects other features, but initial test is positive.

• 5.5 ESXi USB devices and host.

  Hello community,

  I'm just trying to connect a TOUGH USB drive that is connected to the host to a guest operating system and failed!

  The USB device lists via 'lsusb' on the host, but I have no idea how to do to connect it to a guest.

  I got tired by the "Parameters" and "Add Hardware" through the vSphere client and the USB device does not appear!

  If I use the "Connect USB devices" button in vSphere client, I can only connect USB devices connected to the management station.

  Is it possible to connect USB devices connected to the host?

  I hope you can help me!

  Kind regards

  Matthias.

  I just follow advice of jkopp on the change of version vhardware th in thread 5.5 of the ESXi hypervisor free Web Console .

  I just changed to v9 and was able to add my USB HDD to the guest host, so if you have the same problem as me, just spent in HW version 9 and then, you are able to connect devices USB connected host!

  Kind regards

  Matthias

• Single recovery of ESXi host disaster using boot USB device.

  Here's the scenario. I have an ESXi host 5.0 running from a USB device on a server blade using shared virtual machine network storage and is scratch storage. I have a failure catastrophic host. Can I just plug the USB device into another blade in the same chassis and start getting my VMs back operational.

  In addition, in a similar scenario if I have two devices USB with the same configuration information about them can use as a backup in case of failure of the USB device or is it config info constantly being written to the USB device which is used at the time.

  At the level of the configuration, you need not, this means that as long as you take a regular backup of the config, it is ok.

  But when you need to set up a backup system if a production system does not go and change the Server Blade, be sure to provide a coherent zoning and LUN masking for the blade, if VMware will see the same number of unit logic and tables as before. Same thing applies for VLANS, switches to which the new blade is connected must be configured in the same way that the old blade was (its ports must be in the same VLAN), or some VM can't see the network correctly.

  1. If a system is corrupt and you just need a fresh USB boot

  Plug a USB stick fresh, possibly already installed, boot, and then send the archived configuration, reboot

  2. If a full blade goes wrong, you must change the server.

  Put the WWNS of the HBAS in the same areas that the blade HBA has failed

  Present the WWN of the HBA to the storage group

  If you use the same chassis slotin, the network should be ok, but if not, put the internal ports of the switch module blade matches the new blade in the same VLAN as port internal used for blade failed.

  If you use VirtualFabric / VirtualConnect on 10GBE NICs, you must set up the same way, it was too much on the failed system.

  I hope that its more clear now!

• Usb device ESXi 4.1.0 through material passtrough on Dell Poweredge R510

  Hello.

  I am trying to use one of the four usb ports on a Dell PowerEdge R510 inside an ESXi 4.1.0 260247 host for a XP Prof invited. I have the following PCI devices:

  With each of the devices ID 00:1 a. 0 00: 1 d: 3 comments XP correctly will not start. When I attach the 00:1d.7 device boots comments, but then there is a problem with the device driver. I tried the chipset drivers for W2003 from dell (http://support.euro.dell.com/support/downloads/download.aspx?c=de & cs = debsdt1 & l = a & s = bsd & releaseid = R269378 & SystemID = PWE_R510 & servicetag = & os = WNET & osl = GE & deviceid = 17195 & devlib = 0 & typecnt = 0 & vercnt = 2 & catid = 1 & impid =-1 & formatcnt = 0 & libid = 27 & typeid =-1 & dateid =-1 & formatid =-1 & source =-1 & 396483 = starts) , but no luck.

  I know that there is now a direct usb support in ESXi 4.1, but my usb device is not supported through this new feature.

  In addition, I'm looking for a PCI Express RS232 serial card that works on this server equipped with passthrough for a XP guest.

  Thank you

  Michael

  Try to ignore this ridiculous list, it's a bad joke for devices on the external bus like SCSI and USB.

  I've successfully used the USB feature in 4.1 for a device not on the list (in fact, he was a device of type modem/serial port), more precisely a key entropy of Simtec.

  So anyway, try your device with the USB function before mingling with the much more fragile PCI passthrough feature.

• Satellite Pro M70: removal of the USB device causes other peripheral USB does not work

  Withdrawal/use of a USB for a USB device causes devices on USB port to get affected.

  Satellite Pro M70-199 (2 GB RAM)
  Windows XP Pro (SP2) with all updates of Windows installed until end of October 2006.
  This laptop has 3 USB ports.
  An Eicon Diva ISDN USB modem is connected to a USB port.

  When certain devices connected to a different USB port are deleted (even if removed safely with "eject" or "remove device safely", it causes the ISDN modem to file either a double channel (64 k + 64 k) ISDN, or for the ISDM modem to disconnect completely.)

  Cause this include any memory stick USB, MP3 player (ipod and creative zen) and so on.

  Do other devices, such as USB external hard drives & sometimes external DVD USB drives, and sonetimes do not produce this problem.

  Is this a known issue?
  If it is a hardware interrupt problem, how to solve it?
  This problem is related to the modem and the laptop?

  As a note, in addition, intermittent (random) times (cannot reproduce all the time, but it happens once or twice a day) when a USB device is accessible it causes the modem USB ISDN to drop a single channel, even if the lights on the modem still show it as it is connected. In this case and the case above, the only way to get the modem ISDN USB running again is physically disconnect and reconnect.

  The reason why it is a crucial issue is that:
  (1) the modem speed is halved or disconnected
  (2) the ISP continues to full rate for a double load connection even if a channel has been dropped.

  Any help will be greatly appreciated.

  Hello

  I have Satellite M70-159 and I didn t notice any strange problems with the USB ports. I use a few of them as printer, webcam, USB, memory stick, optical mouse, and external HARD drive. The devices are recognized correctly and I always remove without option delete without danger.

  Now I have Vista pre-installed and there is no problem so far. If I understand you right USB ports work fine but there is problem with USB modem only. Am I wrong?
  Also try to contact the producer of modem support. Is perhaps the question like this known and if all goes well, they have a logical explanation.

• Satellite L770 dosen't find USB devices

  Hello

  I just bought a new computer laptop satellite L770 OS windows7.
  I found some problem there, computer doesn't recognize/find/use of USB devices that are connected to the computer.
  I can find the devices in windows, but windows can not use those.

  I can 'remove' sefily of windows device and plug it in again and once more to use it.
  But the problem is that every time I turn on my computer, I have unplug the device and reconnect those, which is really frustrating.
  I tried to find some windows updates and latest drivers for USB or the motherboard.

  I found an update either of those. I wonder if there is hardware problem on my computer. I would be really gratefull for all the advice!

  Hello

  Don t think that his laptop hardware problem
  You should definitely test this with different USB device; Mouse USB, USB HDD, etc.
  I also recommend the settings the laptop configuration using disk HARD recovery option.
  This will outline the laptop in the same State as in the first day of purchase

  It might help to check if this is just something wrong with OS

• USB device can run faster

  Hi all

  I recently bought a USB-6008.  When I plug it into my PC, I get a message "this device can perform faster.  This USB device can perform faster if you connect it to a Hi-Speed USB 2.0 port.  For a list of available ports, click here. "When I click on the message, it shows me a list of available ports, but none of them seem not to be USB 2.0.

  All my USB ports are supposed to be USB 2.0.  It is an Asus P5N72 - T Premium mobo.  I have updated the bios, and made sure that USB 2.0 is selected in the bios Setup.  I use Win XP SP3.  According to the Microsoft Web site, there was a known problem with XP supporting USB 2.0 on Asus Motherboards, but that he was supposed to have been fixed in SP1.

  I realize that it is a matter of Windows probably more than a question of data acquisition, but I spent the entire afternoon on Microsoft, Asus and other sites.  Can anyone help?

  Thank you

  Ed

  USB device not recognized, peripheral unknown.  I can not connect any USB

  If no USB device does not is that you need to install drivers of motherboard (chipset) or your USB ports on the motherboard failed.

• Fix for nasty bug of Sandy Bridge badly on USB devices

  Anyone know if there is a fix yet, some USB devices fail intermittently on a new MB with Windows 7 64 - bit edition.

  It is a quad core running the Sandy Bridge chipset, and vodafone dongles does work, even if they did on W7 64 bit on the former Council.

  Fault too:-some external hard drives are not recognized on any port.

  Your hard drives are connected via SATA?

  There is a known issue with some Sandy Bridge chipsets, where ports SATA fail, don't know if it affects USB ports or not.

  Intel issued a notice of recall for this with the affected chipsets - did you check the Intel website to see if you are one of those affected

• USB device not recognized... Unplug the thing does NOT work

  It baffles me that THOUSANDS of people have this problem, or a variant of it, and no ONE at Microsoft or elsewhere also offers a real solution. Unless of course you want to count the method "unplug your computer", which is the most foolish band-aid for a problem I never heard, even if it works for a lot of people (most). I, unfortunately, am one of those for which the "disconnect" method magic does NOT work. I tried everything what all other posters and responder suggested (BIOS upgrade, change Legacy BIOS definition Enable to disable to activate again, driver updates, uninstall all USB, full power down and restart hours later, use CMD prompt to show only devices, etc.) and do not know what else to try. I would really like to see a REAL answer as to the cause of the majority of the questions posted about the USB error outside the usual "restore your settings, use your restore disk, unplug it, replace your USB key, etc etc etc. HEY! MICROSOFT! SOLVE THE PROBLEM! OR, Hey, here's an idea, a news for you, I'm sure that... don't they exude products until they have been tested (NO! I mean really, fully tested [see XBox 360 RROD])

  In case anyone reading this is a real working solution, I'm on a Toshiba A135-S2386, Vista Home, and each USB port is unusable on any device. All ports feeds the device and noise sounds to indicate that a USB device was attached and then proceeds to the display of the error "USB device not recognized" and shows and shows an unknown device connected. It does this for any USB device.

  FINALLY: PLEASE PLEASE PLEASE DO NOT POST A REPLY IF YOU USED THE METHOD OF "DISCONNECT", AND IT WORKED. Grats to you for fixing your computer, but I can just not read another 400 posts of "wow it worked for me great fantastic" when it does NOT work for everyone. I need something new and real. (Sorry to be all grumpy, but I'm tired of these kinds of problems from companies making billions off the coast of junk, defective, half finished, produced a car!) "You listen to Bill?)

  UPDATE: just ran a scan of the system file Confirmation via an administrator command prompt and it's clean...
  ALSO - was not that before, but now whenever I do a complete power down / reboot thing that it gives me a "Bad Checksum" error and I have to reset the date and time in the BIOS. I need to change the battery in MB? As I said it did not have this before and the USB error was produced, but could this be the problem? Bad battery MB CMOS?

  The bios of your motherboard is probably damaged.

  step 1. See if you can find a previous version of the bios of your motherboard and return date of the bios.

  step 2. Find the latest version of the bios of your motherboard and update your bios.

  Do not use a registered version of your current version.

  To check the problem is the motherboard or operating system. find something like a live Ubuntu CD

  http://www.Ubuntu.com/desktop/get-Ubuntu/download.

  or

  Make a Ultimate Boot CD for Windows

  http://www.UBCD4Win.com/index.htm you are using windows xp or borrow a copy to UBD4WIN.

  Both of the above run in memory (does not load on hard drive.

  Both a bit slow, but are excellent tools.

  Works like a normal computer.

  If you can see you USB devices, magicjack, ETC. your BIOS is not corrupt or motherboard problem.

  In normal windows if you see not the USB devices, magicjack, etc your windows install is corrupt.

  Reload Windows of difficulty.

  If you you do not see the magicjack, USB devices, ETC., your BIOS is corrupt motherboard or other problem.

  Redo your BIOS as described above.

  All other unwanted do not work , he was done !

• Unrecognized USB device if I use more than four devices. WTF.

  Hey,.

  I currently use a 32-bit version of Windows Vista.  I have six slots USB which is given to me.  I use four of them at all times to my keyboard, mouse, WiFi adapter and the headset.
  Whenever I'm trying to plug a fifth device I get the error: USB device not recognized.  However if I unplug any other device, the new device will work perfectly.  And then if I try to re - connect the deleted device back in, it will not work until I have remove the fifth device.
  WTF?

  It is certainly not a question of power that I have decent food.  In addition, why inlcude 6 USB slots if there are only 4 can work at the same time?  I tried Googling for a solution and learned that a computer must be able to handle up to 127 devices, anyway.

  What can I do to fix this error?  Do I have a virus or something?

  Hello

  Check with support of the manufacturer of the system (motherboard for customized systems manufacturer) and ask for their
  Forums about known issues. Look for the updates the BIOS, chipset of low level drivers, and others
  drivers.

  There could be a power problem that the USB interface can supply only so many devices at a time. If
  power is part of the question, then external, powered USB Hub will help.

• But powered USB devices are not recognized

  Randomly on my personal self built computer, readers usb ceased to recognize anything I put in them.  The strangest thing is that the devices kept under tension.  The mouse led would light up and charge the ipod.  I had to plug into an old school mouse and keyboard that do not use usb to use the machine.

  I tried:
  Unistalling/reinstalling usb drivers
  Update BIOS
  Uninstalling drivers for devices (ipod, keyboard, mouse, external hard drive)
  Updated motherboard drivers
  Compensation to reinstall Vista

  I'm really confused on what else to try.

  Data sheet:
  Q6600 2.4
  750FTW
  500 GB WD 7200 RPM hard drive
  2x2gb gskill
  EVGA 9800

  Any ideas would be useful.  Right now, the only thing I can think is to replace the motherboard, but I feel that I would not.  Thank you.

  Hello

  If you can not embedded USB to work then you can disable it in the BIOS and the device
  Manager and use a USB expansion card that is not expensive.

  Check the BIOS settings.
