Hi, I am not sure what you mean by "device file". If you mean a device node, that is a logical file in /dev, you will not find any for the scanner. 1) For the scanner. First of all, make sure your scanner is supported ! I switched from canon to epson because canon scanners were not very welle supported. Then, you have to emerge sane-backends with the usb useflag set. Figure out which backend your scanner use on the sane website (sane-project.org, if memory serves). Then, in the config file of the backend, set the usb id : usb <product id> <device id> For example, I added use 0x4b8 0x110 to /etc/sane.d/epson.conf for sane to detect my epson 1650. If your scanner is always plugged, you'll need to emerge coldplug and rc-update add coldplug default. You might have permission problems at that stage. Check the permissions on /proc/bus/usb/001/007. You must have rw rights to be able to use the scanner. 2) For the CD burner. It seems your cd-burner uses the usb-storage driver. It should then appear as /dev/sdX, provided you configured your kernel correctly. It should be useable at that address. You can do an lsscsi to figure out what to tell cdrecord, but any GUI (k3b...) should be able to detect and use your burner. I hope this helps, -- Jonathan -- gentoo-user@gentoo.org mailing list
