allan, many thanks for Your fast reply. libsane 1.0.9-23 appears to be the very latest version available, so where could I get an ever newer one? All the above versions appear to be up to date, maybe apart from the kernel. If the scanner is a 1.0 USB device, then there could be the real origin of the problem: dmesg tells me that: usb 1-1.2: new full speed USB device using ohci_hcd and address 5 usb 1-1.2: configuration #1 chosen from 1 choice usb 1-1.2: New USB device found, idVendor=03f0, idProduct=0601 usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 1-1.2: Product: HP ScanJet 6300C usb 1-1.2: Manufacturer: Hewlett-Packard usb 1-1.2: SerialNumber: SG06523111PE ... the scanner is considered to be a FULL SPEED USB device, which would mean it thinks it is a 1.1 USB type device instead of 1.0. Is there some way to make the connection a standard USB 1.0 type connection? Btw.: have You used the scanner with its SCSI interface after You noticed the USB problems? Could You fix the problems at all? Regards, Crypto.
