• USB ports are not available

  My host is a laptop Toshiba with Ws 7. The USB ports are fully operational. However, with the players that they are not. for example, XHDD is not on the desktop "XP".

  What to do so I can make use of the USB ports?

  Hi Redoak716,

  You just need to add a USB controller to the hardware of your virtual machine configuration. Make sure VMware tools are installed and running in the comments.

  Once your virtual machine is in place and your USB drive connected to the host, attach it to the guest using the control panel of devices on the lower right part of the screen of the console. It will be detached from the host that it cannot be used by the two systems at the same time.

  It will be useful.

  Is there anyone to show me any solution?

  Thanks in advance,

  Any solution? You mean a magical solution? :)

  No one knows the configuration of the laptop.
  No one knows what OS you are using.
  Nobody knows what you did last time with your laptop.
  No one knows how long you have this problem.
  No one knows what are the USB devices that you use to test USB functionality.

• My usb port does not work. Device Manager says he has a "code 10".

  My dad recently bought a laptop on ebay. It's a HP Omnibook 900 with a 4 GB HD. The previous owner had improved from the original from Windows 98 to XP with SP3.

  It has a USB port in the back & it does not work!

  In fact it is not even appear in the Device Manager! I need to select 'Show hidden devices' to see same the USB hub root. The USB port has a yellow warning icon. In properties, it indicates the port is enabled but does not work because of a "Code 10".

  What the devil is a "code 10" & how in the heck to solve this problem, so that the USB works?

  The port is powered. When I connect devices usb load they turn on & load, but, of course, are not displayed on the computer. My best theory is that the port can be usb 1.0 but the software is intended for usb 2.0 and what could be the cause of the problem. That's just guessing on my part because I do not know with certainty if the usb is 1.0 or 2.0.

  It is especialy boring being the only external devices can I plug a CD player (unwritten) & a floppy drive. It would make my life much more pleasant if I could run software, backup & file transfer, etc. with a usb drive instead! It could even than the laptop quite useful to be worth the bucks thirties, my father paid for it!

  Help, please. Thank you.

  Hi SnarFoo,

  Method1

  The Code 10 error code is generated when Device Manager it has not enough information or error that has spread upward through the device drivers is not recognised by the Device Manager. In addition, this error may occur if one of the pilots who needs the unit does not start. If multiple drivers are used by a particular device, it can be difficult to determine which failed.

  See the article and check if that helps.

  Method 2

  If the previous step fails, then remove and reinstall all USB controllers on the computer and check if that helps.

  To remove and reinstall all USB controllers, follow these steps:

  (a) click Start, click run, type sysdm.cpl in the Open box, and then click OK.

  (b) click on the hardware tab.

  (c) click the Device Manager button.

  (d) expand Bus USB controllers.

  (e) right click on each device under the Bus USB controllers node and then click Uninstall to remove them one at a time.

  (f) restart the computer and reinstall the USB controllers.

  (g) connect the removable USB storage device and perform a test to ensure that the problem is solved.

• Since the L7680 installation my usb ports are not detected...

  It seems that something in the registry has been changed.  My Western Digital Passport (mass storage device) is not detected is not my SanDisk Micro (2G).  Western Digital will work in the USB from the printer, but don't the SanDisk.  I've lost the use of all of my USB ports on my computer processor and montor.  They used to work before installation.  I uninstalled and reinstalled, I check startup items in MSCONFIG.

  I read on the Microsoft support page which the hkey_local_machine\system\currentControlSet\Control...

  should be set to activate, but I do not have this folder in XP.

  Western Digital does not know what is happening, or not SanDisk.  HP really gave me the run around way to uninstall and reinstall, but I didn't get an answer that solves the problem.

  It seems to me that since it was drivers from HP which caused my other unit to pass unnoticed, HP should be able to tell me how to solve this problem.  I do too much research for a new product.  I know I'm very frustrated, and since this is a new printer I still have time to take it for something that's going to work.  I had a Dell that has worked well, I wanted to just an upgrade.  I guess I could have updated by Dell.

  Just about the evacuation, someone has an idea what the fix is for my USB not detected ports that have been replaced by the reader on this printer?

  I added a new HP printer to my set all my ports no longer works. None of my flash drives or removable hard disks worked. I tried everything and then read "ports must be updated". My computer is older than three years and the ports of origin are 1.1 and are of most new USB 2.0 devices. Long story short, I went to microcenter and bought new ports ($11.00) and add them to my computer. All ports are now functional.

• HP Envy m6 1125dx: USB Ports are not working please help

  Hey all,.

  I had problems with my USB ports on my laptop Hp Envy M6 1125 DX. Only 1 usb port works and the rest do not work. I tried everything to update the BIOS updated the drivers from the site. I don't know if the driver is not installed or if it's just a bad USB port, but I didn't really notice it until recently, when I bought a headset and I couldn't use it as my only working port is used by my mouse.

  In the USB tab in Device Manager, it has the following features;

  Generic USB hub

  Generic USB hub

  Family of chipsets Intel (r) 7 series/C216 USB Enhanced Host Controller - 1E2D

  Family of chipsets Intel (r) 7 series/C216 USB Enhanced Host Controller - 1E26

  Composite USB device

  Composite USB device

  USB root hub

  USB root hub

  None of them have a yellow exclamation point so my best guess would be that is missing the drivers for the rest of the ports, but I have no idea. I'm in for this reason excrutiating pain, I'd appreciate any help.

  Thanks in advance!

• Satellite Pro M70 - USB port does not recognize the device

  My Satellite Pro M70 has three USB slots, one on the left and two (vertically one above the other) at the back of the laptop.

  The top slot to USB in the back started giving problems. Sometimes, my computer can't see all that I plugged in there. But if I unplug anything - usually the printer or the mouse - the computer will usually see it then.

  What is the problem? Can do nothing about it?

  My operating system is XP. and my laptop is 4.33 year.

  Thank you.

• Satellite 5005-S504 - peripheral USB are not recognized

  Hello

  with my laptop older, one Satellite 5005-S504, I recently problems with the USB ports. None of the three ports detects a USB device. Device Manager does not indicate a problem on the host controller or root hub.

  I am running Windows XP, SP3 and there was no recent updates to be identified as the cause of this dysfunction.

  Suspicion over there?
  Is there a driver available that could help?

  Thanks in advance!

  TH

  Hello

  The USB ports are listed in the Device Manager or not?
  If so, I'll try to remove them and restart the laptop. After that the ports will automatically install again.

  If it doesn't work, you can try updating the chipset driver. Take a look on the Web from Toshiba site to download.
