I continue to use CONFIG_USB_PRINTER=y, which has worked for me with cups-1.5.0 and 1.5.3. I haven't tried 1.5.4 or 1.6.1 - I suspect that enough has changed in 1.6 for non-OSX users that it might be interesting for some of us (1.3, 1.4, 1.5 were all "interesting" developments for me). But, I don't think 1.5.4 is likely to have changed this. In my case, I avoid usbutils - so, I don't have lsusb installed. In cups we have the following Note: "There is a conflict between the Cups libusb backend and the usblp kernel driver. If you want to use Cups with libusb do not enable USB Printer support in your kernel." So I guess Pol's answer is correct for people who use lsusb. I only use the *browser* to control print queues, so I have no comment on how to invoke lpadmin on the command line - but I assume that the same conflict will prevent it working. ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
