Hello all, This is my first time posting to this list and I'd just like to thank you in advance for any help. A bit about myself: I am a graduate student in Boston, currently building a cluster of flatbed scanners to use for biological data acquisition. I primarily use epson 4990 scanners attached to a Windows box via libusb.
My question regards the manner by which the USB protocol assigns dynamic bus addresses. With five (identical) scanners attached to a single computer, it seems impossible for SANE to keep track of which one is which. Scanimage refers to each scanner by its bus id (i.eepson:libusb:bus-4:\\.\libusb0-0010--0x04b8-0x012a) a number that, accross computer and scanner reboots, changes at random. Is there any way to correctly specify scanners in the face of changing USB bus addresses? I'll have different samples on each scanner and confusing them will cause obvious problems. Is there any way around this limitation? Thanks again, Nick S. -------------- next part -------------- An HTML attachment was scrubbed...
