UPS USB serial device is not detected properly

UPS USB serial device is not detected properly

[Hai Zaar]

Good day! I have Advice Partner PR650 UPS, that connects to PC using USB.
However, /dev/ttyUSB0 is not created. I've tried both on Debian Lenny
and Ubuntu Hardy. Here is what dmesg and udevmonitor say (on Debian):

dmesg:

This is the driver that should bind to this device, but for some reason
it isn't.  Is it also a HID device?  Can you provide the output of
/proc/bus/usb/devices with the device plugged in?

Ah, the hid driver is binding to the device.  You need to add a quirk to
it to prevent this from happening, I don't know why no one has reported
this before.

If you need help generating such a patch, let us know.

I definitely need a help on this and I'll be glad to get some.

Temporary blacklisting usbhid and reloading usbserial and friends did
the trick, but this is impractical solution.
Can anyone provide me a tip how to fix usbhid?

Add it to the big array called hid_ignore_list[] in the file,
drivers/hid/hid-core.c in the kernel source tree.
