pxa270 OHCI usb host problem

[Zachár Balázs <bzachar@xxxxxxxxxxxxxx>]

Hi again,

I have a pxa270 based custom board (I don't know to much about the board)

Originally my board operates as an USB device, but I would like to try it to use as an USB host (I see some success try with other boards on the net)...
I know, the pxa270 have an OHCI controller...

So I cut down the male connector from my board and solder a female to the right position and rewrite a new board driver (use mainstone.c as base) and boot up... (It looks everything work fine now (mmc
reader, network device, nor flash) except the USB host function)

I got these error message at boot (debug usb on, in the kernel):

If I plug in a pen drive to the USB connector I don't see anything (not either in dmesg or in syslog), it look like it didn't detect the plug in...
Where should I search?

regards,
