• Device not recognized-to USB using Windows XP (sp3)

  The camera is on, I did not USB drive internal or external, the USB cable is a direct connection with the camera and the computer. I am running windows XP; I even tried on another laptop and at the end upward with the same message-USB device not recognized! This could be a software problem on the camera, or a bad set of USB cables? The camera is 2 years old and the cable have used about 6 times to transfer photos from the camera to the computer. When I tried on another laptop I got the following message: not properly installed device driver software! Is there a solution to this problem?

• Can I use a USB hub to connect to more of a GPIB-USB-HS USB ports?

  I have an instrument that has a GPIB-USB-HS connected and the USB cable is connected to a USB hub. Can I have multiple computers to connect with USB hub in their respective USB ports? If so, how many computers can I connect using the USB cable?

  I downloaded the latest Driver NI-VISA from the Web site.

  You must first a hub which allows to switch between multiple PCs and PCs as one would at once be connected and in control.

  When you buy this particular type of hub, one of the specifications is how many pc connections there.

• Connection of an instrument with GPIB-USB connection.

  I am trying to use a GPIB-USB adapter to control a unit of Source of LabView. However, I have problems my instrument drivers to recognize the GPIB address specified for the device. I have attached an image below the address specified by IO Keysight connection Expert. I am currently trying to initialized the EMS with the GPIB driver I have attached below. Because of my knowledge limited in LabView instrument control, how should I approach of collecting the correct address of GPIB and recognize it in my VI?

  Hi wyattcurtis824,

  Before we dig into the LabVIEW code, I would recommend a Test Panel of max aperture and trying to communicate with. Are you able to send orders via Keysight connection Expert or NI MAX and see the valid data?

  In addition, when you run the vi in LabVIEW, is pilot it returns an error in the error on the box? If so, what the error is?

• How to get Windows Mobile Device Center to launch a mobile device is connected to the computer?

  Does anyone know how get REALLY WMDC to launch (actually not supposed to) - when a mobile device (MC9090) is connected to the system?

  (Or maybe suggest a request for REPLACEMENT for WMDC - preferably one who "works" with a little more frequency)?

  So far, I tried (many times):

  • Uninstall/reinstall of Windows Mobile Device Center
  • Uninstalling Windows Mobile remote adapter (when checked ENABLE ADVANCE NETWORK FUNCTIONALITY)
  • Uninstall the USB Sync symbol (when ENABLE ADVANCE NETWORK FUNCTIONALITY not verified)
  • Reinstalling WINDOWS 7
  • Using different USB ports
  • Disconnection/connection of device (MC9090)
  • The device and different cradle

  I'm running WINDOWS 7 ULTIMATE x 64.  At some point, the WMDC auto-lancé when the device has been connected - until a few days ago.  Since that time - nothing!

  I lost a couple of weeks on this issue, and this delayed my mobile application development!

• It is supported to connect multiple monitors using USB as a video source?

  Original title:

  USB touch screens

  It is supported to connect multiple monitors (specifically wireless) using USB as a video source?  If so, a hub would be able to handle this or the USB connection should be made directly to the motherboard or the PCIe interface.  Thank you!!!

  Hello

  Thanks for posting your query in Microsoft Community Forum.

  You can buy a switch HDMI that allows you to connect several devices to sources HD (e.g., monitors, TVs etc.) to your computer, while using only one cable HDMI (VGA or DVI) of your computer to connect to the second monitor. So you can get a HDMI switch on your favorite search engine for compatibility information for the switch with Windows 8.1.

  If you want to project, or sharing of the wireless display, you can use the utility Miracast.

  See also the article below to better understand.

  Plug a second monitor or projector

  Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.

  Thank you.

• 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.

• That means "another device on the network use the IP address of your computer"?, that means "another device on the network is using the IP address of your computer?

  That means "another device on the network use the IP address of your computer"?, that means "another device on the network is using the IP address of your computer?

  A

  Most likely, the computer becomes a network address of a router. The assignment of an address ("lease") expires and must be renewed after a certain period of time, which could be an hour or a day. The lease expired without being renewed because the device has been disconnected at the time. Meanwhile, the address has been leased to another device on the network, or maybe the router has not updated its list of addresses the leases. When the device offline comes back online, a conflict results. Depending on the type of router you have, the conflict can resolve itself automatically. If not, then in the menu bar, select please

  ▹ System Preferences network ▹ 

  If the preferences window is locked, click the lock icon in the lower left corner and enter your password to unlock it. Click the Advanced button, and then select the TCP/IP tab in the sheet that drops down. Look at the menu option

  Configure IPv4

  If the selection in this menu is

  Using DHCP

  Click on the button

  Renew the DHCP lease

  Test.

  Make sure that you have more than one DHCP server on the network. That could happen if you have more than one access point Wi - Fi, or if you have a router and broadband a wide device distinct in connection mode sharing.

  B

  Less likely, you have a network address that you assigned yourself and another device is itself by assigning the same address. In this case, the selection to configure IPv4 menu will be either manually or using DHCP with manual address. This kind of conflict will not be resolved automatically. You have the following options to solve:

  1. Change the selection in menu using DHCP.
  2. Change the address assigned manually to one that is not used by another device.
  3. Change the address of the other device.

  Which of these options you choose depends on the details of why you use a static IP address. Any changes you make to the network settings is necessary before taking effect. To do this, click OK, and then click apply.

  If the router is also your device at wide band, then he may be operating in bridged mode. In this case, only one customer at a time will be able to connect to the Internet. Consult the manufacturer or ISP documentation for how to reconfigure the device in the connection mode sharing.

  C

  According to a report a "DirectTV" receiver can cause the problem. If necessary, disconnect the device from the network, or power off and test. Consult the support services provider.

  Microsoft has agreed that there are some issues with the USB 2.0 driver and registry. This problem still exists on the laptop centrino duo?

  It is not known to me and I can t believe that self-government will reduce by 80% when the USB device is connected.
  Is the USB ports power USB devices.
  Of course, additional USB devices waste the energy of the battery and battery working time is shorter if USB devices are connected.
  But it s not 80%

• Windows crashes when any USB device is connected

  Hello

  I have a laptop Dell Latitude D505 with Windows XP. Recently, whenever I plugged in a USB device, Windows would freeze and I have to hold the power button down to turn it off.  Since then, I tried to replace the RAM, re - install Windows on a new HARD drive and taking the other components (Wi - Fi, CD). I still don't understand why it freezes. Any ideas?
  Thank you very much!

  Hello

  1. don't you make changes to your computer, after which the issue started?
  2. have you tried to connect USB devices to a different USB port? If so, they work on other ports?
  3. have you tested the USB devices on another computer?

  Uninstall and reinstall the usb host controller driver and check if the problem persists.

  I would recommend that you update your BIOS and drivers from the chipset and check if the problem persists.
