[dump log incl] usb - stick initiates crash

hi,
on my mothers pc (dual core intel, hp media center with windows XP media center, SP2), the system crashes if we try to use certain usb sticks. the sticks work perfectly on other devices, and we even formatted them, without any change.
The system recognises the stick, but when we try to write of read data from them, the system reboots on its own.

below there is the log file from the last crash...

thank you for your time and assistence,
grtz duckie and mom
