Re: Member of administrators to connect a USB Flash Memory ? Why ?

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

The secret ins in the log file: C:\Windows\setupapi.log
When you plug new USB devices every event is written there.

In my case i had problems with the digital signature of
C:\WINDOWS\system32\setupapi.dll

You can use Start-Run sigverif to verify file signatures.

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

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..

they work with Power User privilegies and Windows XP SP2 is requesting

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