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.
