I just picked one of these up to replace my 4315, which broke (I think the feeder roller gear broke from an overstuffed feeder), but it's giving me problems. I had no trouble configuring it to print, but it doesn't appear in lsusb and xsane can't find it, so I can't scan with it, which is the main reason I bought it in the first place. I've tried restarting the autofs service (automounter), rebooting, and switching the USB cables with my old HP Scanjet 3300C, but the 3300 shows up on either cable and the 6500 doesn't appear at all. I checked in Google and saw other issues with the 6500, but this wasn't one of them. Any suggestions? I suppose I could get a switch and hook it up via Ethernet, but that really isn't a good solution, and it doesn't explain the problem. Thanks. Mark
