If I connect an USB token to my at91rm9200 board I get:

dmesg:
uhub0: device problem (STALLED), disabling port 1

booting with USB token connected:
uhub0: <Atmel OHCI root hub, class 9/0, rev 1.00/1.00, addr 1> on usb0
uhub0: 2 ports with 2 removable, self powered
uhub0: device problem (STALLED), disabling port 1
uhub0: device problem (IOERROR), disabling port 2

NB: port 2 does not exist

but if I connect the device immediately after ohci detecting:

dmesg:
ugen0: <ActivCard S.A. Token-USB, class 255/255, rev 1.10/1.00, addr 2>
on uhub0

# usbdevs -v
Controller /dev/usb0:
addr 1: full speed, self powered, config 1, OHCI root hub(0x0000),
Atmel(0x0000), rev 1.00
 port 1 addr 2: low speed, power 100 mA, config 1, Token-USB(0x0003),
ActivCard S.A.(0x09c3), rev 1.00
 port 2 powered


This happens with all tokens I have.
It looks like something broke the ohci controller.

Is there someone who successfully use usb on at91rm9200 board with
- -current?
