Sometimes the device that gets noticed by usbd is not the device that you eventually want. For instance, I have a usb pendrive. When I plug it in, usbd sees a device called umass0. But what I'm interested in is the adXsY device that represents the partition on the drive. So in this case usbd isn't very helpfull. I've asked this before, but you never answered; If you plug in the scanner in a running system, do you see it in the 'dmesg' output? If you do _not_ get a message like: uscanner0: EPSON EPSON Scanner, rev 1.10/3.02, addr 2 in your dmesg after you plug in the scanner, I'd say that your kernel doesn't recognize the scanner for some reason. This would be a bug in 4.x. If it does appear, the scanner is found by the kernel. If the scanner does not work in this case, what exactly is the reported error? If you've not running devfs, and the scanner wasn't available at boot time, maybe the the device node was never created? Can you confirm that the device node for the scanner exists if you boot up without the scanner present? > Can anybody out there use the 1650 under 4.x without the need to > connect it _before_ system startup ? =20 I haven't run 4.x, because it doesn't support my amd64 system. :-) > Roland,do you need to reboot > under 5.3 if you connect it to the running system ?=20 No, its works like a charm.
