I'm trying to set usb host up on our board (LH7A400 + ISP1160). It already works to some extend; it detects my Kingston 1GB stick. But then it (usb reset) fails with "Request Sense returned 00 00 00". Funny
Does your stick work correctly before resetting it? Can you read a file into memory and verify it was loaded correctly?
thing is that it starts to work if I enable debugging messages in usb_storage.c and isp116x-hcd.c. If I enable them in usb_storage.c only, it doesn't work. Here is the debug message log with debugging enabled in usb_storage.c only till the first difference I can see:
U-Boots USB implementation is known to have some timing issues which havn't been fixed yet. You'll have to experiment to find out whats causing your problems. Have you tried defining ISP116X_HCD_USE_EXTRA_DELAY?
Did you miss to add some board specific initalization?
Best regards
