Shouldn't it be possible to use the existing viceo backend at least to understand what's send to the scanner? That backend claims to support that scanner. > Ahh !

On the other hand, if it has such grave bugs it may be better not to link to it. > I guess OUT OUT should be usb_bulk_write and OUT IN should be usb_bulk_read Yes. These are URBs, not the actual physical data on the USB. That means that the data is just read and not that a buffer filled with zeros is sent to the scanner. Also, you can tell if its a read or write by looking at the endpoint number (if bit 7 is set (0x80), it's an IN endpoint). Bye, Henning
