With all of the patches that I just sent, I tried out the driver and it
didn't work :)
Here's the dmesg messages that I get when I plug in a hub to the ohci
controller:
ohci-hcd.c: USB Schedule overrun
<repeated lots of times>
usb_control/bulk_msg: timeout
ohci-hcd.c: 00:09.0: ohci_get_frame
ohci-dbg.c: UNLINK:[726f] dev:0,ep=0-O,CTRL,flags: 0,len:0/0,stat:-2
ohci-hcd.c: USB Schedule overrun
hcd.c: giveback urb ec24ec20 status -2
hcd.c: 00:09.0: wait for giveback urb ec24ec20
usb.c: USB device not accepting new address=3 (error=-110)
ohci-hub.c: 00:09.0: GetStatus roothub.portstatus [1] = 0x00010100 CSC PPS
This same hub works just fine with the usb-ohci, uhci, and usb-uhci
drivers.
One other comment, it looks like you got the "Product=" and
"Manufacturer=" lines in /proc/bus/usb/devices backwards :)
thanks,
