from netbsd via dlg, umass.c revision 1.97:
Well, this is bloody obscure...
My Imation USB FlashGO! adapter responds to a Get Max Lun request with a
stall. With uhci, this does the expected thing. With ohci, it was returning
a "data underrun" error because we weren't setting "buffer rounding" (i.e.
USBD_SHORT_XFER_OK), and the underrun was taking priority. This happened with
both the ohci in a Mac cube and the builtin ohci on the S3C2410.
So, set USBD_SHORT_XFER_OK on the Get Max Lun. Now I get a stall reported and
umass attaches correctly.
