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.

Yes, both ISP116X_HCD_USE_EXTRA_DELAY and ISP116X_HCD_USE_UDELAY.
Without those it didn't even detect the stick.

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
