Hello All I have ported linux 2.6.12 USB driver to 200MHz MIPS SOC with synopsys USB 2.0 block. The USB block is NOT interfaced using PCI therefore I used platform glue structure to port the driver. The driver is now working.
I am facing issues when using a 2.0 external HARD disk or flash drive. I can copy small files(less than 500k) to and from the disk without any issues. Large file transfer(greater than 1MByts)takes long time to finish and as a result the console gets locked giving impression that USB is hanging. Attempts to do file transfer larger than 50MBytes results in bus reset message by the driver. During the file transfer scsi_eh_0 and usb-storage alternates between S and D state as reported by top command. The endpoints are halted and cleared during transfer as is evident from dmesg below. # dmesg -c usb-storage: -- transfer complete usb-storage: Bulk command transfer result=0 usb-storage: usb_stor_bulk_transfer_sglist: xfer 512 bytes, 1 entries usb-storage: Status code 0;
