I've also installed the linked kernel today, and verified it works for me as well! The keyboard was detected correctly every time through multiple unpluggings and reboots, with output similar to what Frits pasted above. I too always get the "couldn't find an interrupt endpoint" message, but other than the device seems to work well.
I'll keep using this kernel and will report if the problem appears again.
