Hello,<br><br>First off let me say that I am an absolute novice when it comes to any kind of a command line interface, so go easy on me.<br><br>Here's my problem. I have installed: sane backends 10.0.18 and libusb 0.1.12
<br><br>on a G4 macintosh running MacOS 10.3.9 and I can't get my scanner to work using scanimage. <br><br>This is what happens:<br><br>Andy-Whelans-Computer:~ andywhelan$ sane-find-scanner<br><br> # sane-find-scanner will now attempt to detect your scanner. If the
<br> # result is different from what you expected, first make sure your<br> # scanner is powered up and properly connected to your computer.<br><br> # No SCSI scanners found. If you expected something different, make sure that
<br> # you have loaded a kernel SCSI driver for your SCSI adapter.<br><br>found USB scanner (vendor=0x067b, product=0x2303) at libusb:001:003-067b-2303-00-00<br>found USB scanner (vendor=0x04b8 [EPSON], product=0x011f [EPSON Scanner]) at libusb:002:002-04b8-011f-ff-ff
<br> # Your USB scanner was (probably) detected. It may or may not be supported by<br> # SANE. Try scanimage -L and read the backend's manpage.<br><br> # Not checking for parallel port scanners.<br><br> # Most Scanners connected to the parallel port or other proprietary ports
<br> # can't be detected by this program.<br><br> # You may want to run this program as root to find all devices. Once you<br> # found the scanner devices, be sure to adjust access permissions as<br> # necessary.<br>
<br>Which sounds okay to me. Then:<br><br>Andy-Whelans-Computer:~ andywhelan$ scanimage -L<br>[sanei_debug] Setting debug level of snapscan to 2.<br>[snapscan] add_usb_device: error opening device libusb:002:002-04b8-011f-ff-ff: Invalid argument
<br><br>And that's all I know. It sounds to me like SANE doesn't like what it's getting from libusb, but like I said, I'm pretty inexperienced with this stuff.<br><br>Any help would be greatly appreciated.
