Yes, I think this is about the best you can hope for with that drive. If only we knew how to prevent it from crashing so often -- but maybe there is no way to prevent it. I wonder what would happen under Windows? > Do you need the usbmon output of it ... it is big, uncompressed 156M.

So doing the immediate reset for OUT transfers would affect only half of the problem. Maybe doing it for all transfers would be okay; I'm not sure. I'll have to ask on the usb-storage mailing list. > I will be on and off till next sunday since I have a congress. So don't > expect any immediate answers from me. I can't think of anything else to try. For now there doesn't seem to be anything to do but chalk it up to bad firmware.
