I'm no scanner/sane specialist, but do remember a printer will even work with a unidirectional parallel port, data just going computer to printer, whereas a scanner feeds a lot of data back, (PC BIOSes have various EPP/ECP etc modes, some modes support nibble mode too, ie 4 bits each way for a PL-IP connection etc), So maybe your USB to parallel device may need to support bidirectional (if it can), & may need to be told to configure itself in bidirectional mode etc. How you might set about doing that I cound't advise, but would depend on your device manufacturer & which Unix you are using, & whatever it's USB control vagaries might be.
