Post USB hotplug
Why all USB devices requires hotpluging? After booting only one device is visible, only that one which was used for booting (SD card or hard disk), all other devices are not usable even if they are properly detected during startup. After removing and inserting again each USB device everything works fine (I have tried this with USB mouse, USB remote control, USB external card reader). Is it something wrong with my trim slice or is it software issue? Any chance to initialize USB devices on startup? I have tried original kernel 1.01 and latest one 2.01, behaviour the same.

BTW. On serial output sometimes I can see some IO errors related to one of USB slots.

I did get a usb hub for my keyboard and mouse, reason being the usb port where I had my mouse plugged in will go away (never to come back), not sure why the hub prevents this from happening but since it works I didn't dig more into it.
