Subject[USB] hid blacklist addition for the BerkshireProducts USB PC Watchdog
Hi Vojtech,

the hid driver oops'es on the BerkshireProducts USB PC Watchdog card
when it automatically disconnects itself, just before doing it's
reboot stuff. (See Oops log at the end of this message)

The (quick) fix in this case is to add this card to the hid blacklist.
(See diff below).

I added the change to the linux-watchdog bitkeeper tree
(See http://linux-watchdog.bkbits.net:8080/linux-2.5-watchdog
ChangeSet 1.1436).

Some more info:

[USB] hid blacklist addition

Added the Berkshire Products USB PC Watchdog to the hid blacklist.
This to avoid problems with USB-Disconnects when the card feels it should reboot...

Greetings,
Wim.
