Could you post please the exact error message (for my records
and for investigation).
One more thing to check is filter drivers.
For an USB drive we deal with an USB device, an Disk device
and a storage volume.
The filter drivers are found in the registy under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class
Here are keys with the GUIDs of device classes.
USB devices are {36FC9E60-C465-11CF-8056-444553540000}
default: no LowFilter, no UpperFilters
Disk devices are {4D36E967-E325-11CE-BFC1-08002BE10318}
default: no LowerFilters, UpperFilters = "PartMgr"
Storage volumes are {71A27CDD-812A-11D0-BEC7-08002BE2092F}
default: no LowerFilters, UpperFilters = "VolSnap"
Try to restore these defaults, log on as restricted user
and try to attach an USB drive...

Sorry Sieber, it did not work neither, I also practiced Microsoft methods 1,2,3,4,5 y 9 of Microsoft's troubleshooting for USB pen drives under Windows XP.
I'm thinking it's related to specific soft in new fujitsu laptops, i did not format to go step by step yet, but only users of new fujitsus have report this problem, while everybody in the network is working as Power User, with the same enterprise standard installed programs.
Thanks a lot..
PD. I would like to have an idea of the registry entries checked when pluging memories..

It says "You must be a member of Administrators in order to connect..." whenever Cancel is pressed in the dialog that appears.
XP cannot validate its own driver's digital signature.
