Hey all,
just got my raspi today and started it up with a fresh archlinux arm archlinuxarm-29-04-2012.img
Everything worked great, got xorg and all working at resolution of 1600x1200. However after rebooting after full system upgrade, my wireless USB keyboard became pretty much useless. Something like 30% of the key events seem to go amiss, so key presses don't print out at all or end up repeating the same character when the key up is not registered.
I'm aware of this http://elinux.org/RPi_VerifiedPeripherals and that there has been some issues with certain keyboards. However since the keyboard works fine with the stock image, I assume there's a bug lurking somewhere that can be fixed.
I got a 1200mA power supply and the voltages on board seem rather steady at 4.88V. Having the wireless usb dongle connected/disconnected doesn't seem to make any difference to voltage, so I'd personally rule out power supply issues.
The keyboard is some weirdly branded "Prodige FlatX Mini".
Anyone else had such issues? Should I drop a bug report on github? Any ideas what I could try to investigate still? Ideal would be of course if I could find out the exact package upgrade causing the problem..

Symptoms seemed to appear after upgrading libusb and libusb-compat.
