[...] [avision] attach: sending INQUIRY [avision] try to write cmd, count: 6. [sanei_usb] sanei_usb_write_bulk: trying to write 6 bytes [sanei_usb] 0000: 12 00 00 00 60 00 ............... I'm really no avision expert but that's the first command that's sent to the scanner. While the uscanner driver can't cope with control messages, bulk messages should be ok. So I'm a bit surprised that it fails there. > Beside, how do I use libusb on 5.2?

At least on Linux, libusb only works if the scanner is not claimed by a different driver, e.g. uscanner. So you must tell uscanner not to detect your scanner. I don't know if that works without recompiling without uscanner support. I guess ugen will getect the scanner once uscnner doesn't and the device will show up. Bye, Henning
