This quirk disables the volume keys. I don't know how the device looks like, but wouldn't it make more sense to actually remap the bogus keys it's sending to produce KEY_VOLUMEUP and KEY_VOLUMEDOWN?

I've setup a script to remove and reinsert the usbhid module and then run evtest on that event and found the following: Event: time 1353511306.254194, type 4 (EV_MSC), code 4 (MSC_SCAN), value c00e9 Event: time 1353511306.254199, type 1 (EV_KEY), code 115 (KEY_VOLUMEUP), value 1 Event: time 1353511306.254227, type 4 (EV_MSC), code 4 (MSC_SCAN), value ff010002 Event: time 1353511306.254229, type 1 (EV_KEY), code 259 (BTN_3), value 1 Event: time 1353511306.254241, -------------- SYN_REPORT ------------ Event: time 1353511306.414246, type 4 (EV_MSC), code 4 (MSC_SCAN), value c00e9 Event: time 1353511306.414250, type 1 (EV_KEY), code 115 (KEY_VOLUMEUP), value 0 Event: time 1353511306.414283, -------------- SYN_REPORT ------------ Whenever the EV_KEY event BTN_3 code occurs, then I can no longer click on various items. I'm assuming the input system thinks that a 3rd mouse button is down and never released. Where would be the proper place to quirk this particular headset? The goal would be to still have the EV_MSC/EV_KEY events for proper codes such as KEY_VOLUMEUP and KEY_VOLUMEDOWN, but ignore BTN_3 events since the headset device only has two buttons for adjusting volume. I have actually seen a few other bug reports of other devices that have this quirk so I think this might affect more than one device; however at this point I only have one that I can verify myself.

When an SB Arena USB headset is plugged in, it registers the volume keys on the headset as a keyboard and continually sends events causing issues with normal keyboard input. This quirk disables the volume keys.
