USB keyboard losing keystrokes in 2.6.34.2+

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If the keyboard has been idle for a while, it's dropping the first
keystroke when you start to type. And booting with
"usbcore.autosuspend=-1" makes the keyboard not accept any input at all.

Reverting commit 3d61510f4ecacfe47c75c0eb51c0659dfa77fb1b ("HID: usbhid:
enable remote wakeup for keyboards"), added in 2.6.34.2, fixes the
problem.

2.6.36-rc2 does not have this bug, but I can't figure out what changed.
