Hello
I'm encountering a big problem with usbhid-ups driver : the driver hangs
after loading some other modules (stale data message) !
And we can't restart it.
We load :
i2c-piix4
adm1021
adm9240
lm75
The unloading of the modules doesn't solve the problem.

exec: /lib/nut/usbhid-ups -a ellipse -k
Network UPS Tools - Generic HID driver 0.34 (2.4.1)
USB communication driver 0.31
Startup timer elapsed, continuing.../
After I've unplugged the ups from the usb port, lsusb has hanged too !
And the load average increases :
/load average: 10.24, 8.64, 6.58/
Is there a solution to kill these processes ?
kill -TERM, -QUIT or -9 don't work !
We are using nut 2.4.1-r1.
Any suggestions ? Is this a known bug ?
Thanks for your help.
Regards, Frederic
