Hi Aaron, > 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.
Tried different kernel versions: From 2.6.15 to 2.6.17. Didn't make any difference > 2. In case the printer is confused or hung, power-cycle printer. Yes, tried that too, but didn't help either. The strange thing is, although I get these DOT4 Errors the printer works fine using usb:// backend and also the supply status is shown correctly in hp-toolbox, I just can't print anything. > 3.

All cables work well in WinXP and with the usb:// backend. > 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. Hmm, I'll try, but if I remeber correctly my BIOS has no such option... > If still getting dot4init errors, get the following info so we can try > to reproduce the problem. These errors occure on two different systems, on my intel-based notebook and on my AMD-based desktop-system. My notebook is a Sony Vaio Z1 with the ICH4-M Southbridge and 855 PM Northbridge. My desktop system is based on the Epox 8RDA3+ with nForce2 Chipset (MCP Southbridge). On both systems Gentoo Linux is used. > 1. What kind of mother board is used? > 2. What USB chip set is used? > 3. Distro? > lspci -v | grep HCI Unfortunately I won't be home before friday so I can't give you the output of lspic. I hope the info about my systems is sufficient, otherwise let me know and as soon as I'm back I'll post the output of "lspci -v | grep HCI" For reference: http://www.mail-archive.com/[email protected]/msg00080.html https://launchpad.net/products/hplip/+ticket/1418 So this problem (especially wiht the CLJ2550LN) seems to be present since quite some time for other people, too.
