Dear Timo,
Does your stick work correctly before resetting it? Can you read a file into memory and verify it was loaded correctly?
What kind of reset do you mean? I think I have to do 'usb reset' first. I have not tried to read a file but 'fatls usb 0:1' gives a proper listing but ONLY when I have debugging enabled in isp116x-hcd.c.
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?
Yes, both ISP116X_HCD_USE_EXTRA_DELAY and ISP116X_HCD_USE_UDELAY. Without those it didn't even detect the stick.
Did you miss to add some board specific initalization?
I would think not because it at least detects the stick; it says: "1 Storage Device(s) found"
Meanwhile I learned a little more: It seems to fail at request sense command but I can't see exactly how because the problem evaporates when I enable more debugging. After that command, usb_storage.c says:
DATA phase
usb_bulk_msg error status 32
