Windows 7: USB and External Memory problems in Win 7 - available, but not showing

USB and External Memory problems in Win 7 - available, but not showing

I have a Kingston G3 USB Device, however this issue happens with 99% of memory devices I plug into my desktop, running Win 7.

Other USB devices works fine, joysticks, printers etc. However the external memories, flash drives all have the same problem in 99% of the times. When plugged in, they do not show in My Computer, checking Device manager, they do show up, however with a yellow triangle.

I try updating drivers and troubleshoot, but nothing changes. I check in Control Panel - Device and Printers, and it is showing there under Devices, and status it is working properly. But as mentioned before I can not access the device. I than checked in Disk management, and I can find the Device in Disk 6, does not have any driver letter attached to it.

If I Right Click, and choose the option to change Drive Letter and Path, I get an error message, which reads:

The operation failed to complete because the Disk Management console view is not up-to-date. Refresh the view by using the refresh task. If the problem persists close the Disk Management console, then restart Disk Management or restart the computer. (I have done that but it doesn't help)

If I try to Format the disk/flash drive, I get the following message: An unexpected error has occurred. Check the System Event Log for more information on the error. No options in the Blue Box area is working, if I click in the Disk 6 Box, it allows me to see the properties, and confirms all is working fine. But will not allow me to make any changes to the drives letters. Now this happens on my factory Win 7 desktop, if I plug the same device in to my laptop it works fine, no issues at all.

In the Disk Management section it says: Disk 6- Removable, Online - and size of the disk. The issue is that this is a problem with any external hard drive I connect to my desktop, with very few exceptions. Please anybody any advice to resolve this problem?

(My laptop uses XP op system) I just tried opening XP - mode in my Win 7, virtual computer, and the USB stick is detected there, in XP, but not in Windows 7.

(By the way if I check Device Manager, with the yellow triangle, it comes up error 28, however this is only place where there is an issue with the device, other wise no information comes up.)
