More info?)
Hi,
It seems that quite a number of people have exactly the same problem :
a) USB mass storage disk works correctly on all PCs
b) All the sudden (security fix or what ?) they are shown as 'unrecognized
devices' on ONE of the computers, but still work on the other XP SP2 computers
c) Other USB has no problem, only mass storage devices.
I have two Freecom USB disks, and an Apple iPOD 60 GB, all doing the same on
my main computer, but all OK on my other machines (Portable in USB 2, old PC
in USB1.1, office desktop USB2)
Could you please have this become a case for Microsoft ?
You can also quote the threads 'XP Pro and USB memory Devices','no driver
for mass storage devices' and quite a number of others - just look here for
'unknown usb' or just Google for it.
In the following thread only, multiple persons have the same problem
http://forums.devshed.com/t124914/s.html
This CALLS for a Microsoft proper investigation and solution.
