OK, it really seems to be a timing issue. I have now a correct 'fatls'
output with all debugging disabled. I added one delay into the
usb_stor_BBB_transport function like this:

	if (srb->datalen == 0)
		goto st;
	USB_STOR_PRINTF("DATA phase\n");
-->	wait_ms(200);
	if (dir_in)

100 ms was too short.

Now the question is, what is the correct way to fix this?
