If you plug in an USB keyboard after boot, without suspending in forehand,
it works as expected. dmesg reports a new full speed usb hid device etc.
However, if you suspend, it breaks the usb driver or something. No
reaction in dmesg what so ever.
How to replicate:
1# boot
2# change to usb host
3# plug in keyboard, -It works.
4# reboot
5# change to usb host
6# suspend and resume
7# plug in keyboard, -Noting happens.
This has effected every distribution and kernel I've tried:
FSO M1/2/3/4, OM 2007, ASU, 2008.8/9
I really need to use a keyboard so this is kinda crucial for me.
Extract of dmesg:
soc-audio soc-audio: starting resume work
soc-audio soc-audio: resume work completed
usb0: no IPv6 routers present
s3c2410: changing usb to host
#Here i plug in the keyboard, nothing happens (This would be step 7 in the
descr. above.)
s3c2410: changing usb to device
usb0: no IPv6 routers present
