Hi all,
I am trying to port usb_ohci code (u-boot-1.1.3 version) from 
cpu/arm920t/s3c24x0 to our chip.
I added low_level specific functions and It seems to work correctly with 
a low
speed device (mouse...).
Things get a little more compilcated when I use a disk-on-key.
when I perform a : usb start

U-Boot> usb start
(Re)start USB...
USB:   scanning bus for devices... 2 USB Device(s) found
       scanning bus for storage devices... ERROR: CTL:TIMEOUT

But when I perform a usb tree I get this :
U-Boot> usb tree

Device Tree:
  1  Hub (12MBit/s, 0mA)
  |   OHCI Root Hub
  |
  +-2  Mass Storage (12MBit/s, 94mA)
       M-Sys DiskOnKey 2730C3409173AB63

or a usb info :

U-Boot> usb info

But when I perform a usb storage I get this :

U-Boot> usb storage
No storage devices, perhaps not 'usb start'ed..?



Do you know why all this mess around the disk-on-key ?

Do you know how to solve this ?

Should I try code from cvs instead of that of 1.1.3 version ?

Best regards,

Amine.
