Hi Florian, thanks for detailed report. Seems to me that this is more probably related to USB layer than to HID layer, because of the USB HUB disconnect/connect messages.
I have put linux-usb-devel on CC. For those who missed the original thread, it's on http://lkml.org/lkml/2006/12/25/35. I include Florin's way to reproduce the problem below, as it didn't go to the list. Florin, maybe you could rather try git bisect to trace down the commit between 2.6.19 and 2.6.20-rc1 that causes your USB keyboard to go "offline", in case that reverting my HID core patches produces no meaningful result. Will try to reproduce the problem at my side anyway.
