isp1362

Hi,

to realize a usb-host on 8270 we use the isp1362 and the working device driver of the denx kernel.
A little code and the 82xx can talk with the usb host.

The boot messages are

...
usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
isp1362-HC Detected
usb.c: new USB bus registered, assigned bus number 1
Product: USB OHCI Root Hub
SerialNumber: c7f4b000
hub.c: USB hub found
hub.c: 2 ports detected
isp1362-HC Initialization Successful
...

It seems it is initialized well.

But if i connect a device on the usb bus it is not able to address the usb device.
It outputs :

hub.c: new USB device L-1, assigned address 2
usb_control/bulk_msg: timeout
unlink URB timeout
usb.c: USB device not accepting new address=2 (error=-110)
hub.c: new USB device L-1, assigned address 3
usb_control/bulk_msg: timeout
unlink URB timeout
usb.c: USB device not accepting new address=3 (error=-110)

Maybe interrupt handling ??

Any ideas ?? All hints are welcome.

Thanks in advance
Marco
