The log looks fine IMHO.

The autosuspend shouldn't be the culprit, as it should definitely be 
turned off by default for mice and keyboards (could you please verify that 
it really is)?

I any way, the autosuspend for HID has been implemented by Oliver and is 
currently sitting as 8390887fae ("HID: autosuspend support for USB HID") 
through which it gets to -next. Could you please verify that this patch 
really isn't the culprit?

Thanks,
