Markus, Here are some things we can try..
1. For USB High speed support, make sure you are running kernel 2.6.15 or higher. Depending on the printer (ie: CLJ2550, CLJ2840, LJ3050, LJ3055), older kernels may only work with USB Full speed. 2. In case the printer is confused or hung, power-cycle printer. 3. Some inexpensive USB hubs do not work well with 1284.4/MLC. Try with USB cable plugged directly into PC, no USB hub. 4. If the printer is enumerating as USB High speed, try Full speed. Either set bios to use Full speed or use USB 1.1 hub. If still getting dot4init errors, get the following info so we can try to reproduce the problem. 1. What kind of mother board is used? 2. What USB chip set is used? 3. Distro? lspci -v | grep HCI Hope this helps! A Markus Huschka wrote:
