I am unable to access USB devices such as a WD HDD or Flash disks running
Windows XP Pro SP3. However, I found that if I open a guest VMware Windows
XP Pro SP3 on this same laptop and plug in the devices, they come up as
expected in the Host... so it is clearly not a hardware issue as the
undlying hardware is identical.
Anyone have any idea what would cause this?
Here is the output from USBView.exe:
