The USB devices (mouse, keyboard, USB stick) are only found during the first boot. After reboot, they don't work. Seems the system doesn't found them. Please see the attached logs.

When remove the file /etc/udev/cache.data and reboot, the USB devices can be found and work again.
Comment 8 Paul Eggleton 2014-06-19 14:51:36 UTC 
I could be wrong but this kind of sounds like a generic udev cache problem rather than being something device-specific. Do we see this with other machines?
Comment 9 Denys Dmytriyenko 2014-06-19 15:35:54 UTC 
Yes, it is udev cache related. But I believe it used to handle USB devices properly before... Anyway, I've been looking into it, trying to make it work w/o disabling udev cache completely.
Comment 12 Denys Dmytriyenko 2014-07-03 14:43:30 UTC 
The fix is in OE-Core master
Comment 13 Yi Zhao 2014-10-29 06:45:30 UTC 
Verified with 1.6.2 rc1
