[sane-devel] USBDEVFS_BULK failed errors - Epson Perfection 2400 Photo

[Karl Heinz Kremer]

David,

I don't think that this is a Sane problem, the message you get is
from the USB system.

If you have more USB ports on your system, try a different port, if
you have the scanner connected via a hub, try to connect the
scanner directly. Try a different USB cable. If you have access to
a USB PCI card, put that into your computer and give it another
try.
