Hello,
since kernel 3.2 I have a problem with my Antec Fusion V2 knob and the imon driver.
Imon.ko detects correctly the knob and it creates the device under /dev/input/event/by-id.
If I do a cat of usb-15c2_ffdc-event-if00@ device and I move the knob, I don't see any output.With 3.1 kernel it works correctly instead.

dmesg |grep imon

[    2.646211] imon 6-1:1.0: 0xffdc iMON VFD + knob, no IR (id 0x35)
[    2.791264] Registered IR keymap rc-imon-pad

[    2.797361] usbcore: registered new interface driver imon

I'm using Slackware 13.37 32bit.
I've tried also 3.2.1 version of kernel,without any effect.
What's wrong?
