<div>====ThinkPad T30 model 2366-M1U====<br />
*BIOS Version 2.08<br />
*Embedded Controller Version 1.06<br />
<br />
====Currently Running a Dock II model 2631-20U====<br />
*Debian sarge with Linux 2.6.10-4 from sid<br />
<br />
When the laptop is running in the dock, the USB ports are not fuctional. This is the only error that I have seen in the kernel.<br />
*hub 1-0:1.0: Cannot enable port 1. Maybe the USB cable is bad?<br />
It doesn't matter whether a device is plugged into one of the two USB ports on the back of the dock.<br />
<br />
My original dock worked just fine. The problem only seems to exist with my new dock when running Linux. The Dock's USB ports do work in Windows XP. I have tried various kernel versions through out the last few weeks. Is anybody else having similiar issues?<br />
<br />
Tested with Knoppix 3.7 running Linux Kernel 2.4.27<br />
When the mouse is plugged into the top port on the dock, I get this error:<br />
*hub.c: Cannot enable port 1 of hub 1, disabling port.<br />
*hub.c: Maybe the USB cable is bad?<br />
When the mouse is plugged into the bottom port I don't get an error, but the mouse isn't detected either. When the laptop is not plugged into the dock and a mouse is plugged in, the last two lines reported by hub.c are:<br />
*hub.c: new USB device 00:1d.1-2, assigned address 2<br />
*usb.c: USB device 2 (vend/prod 0x45e/0x39) is not claimed by any active driver.<br />
instead of the two lines mentioned above. The mouse works when a Dock is not involved.<br />
*[http://www.college-paper.org college essay]<br />
The Linux 2.6 kernel that Knoppix 3.7 uses behaves almost identical to the 2.4 kernel.<br />
<br />
Windows XP Pro works with the Dock 2631.<br />
<br />
When testing my T30 on a Port Replicator model 2878, the Dock's USB ports work.<br />
<br />
When testing my T30 on a Dock model 2531, the Dock's USB ports did not work.<br />

====ThinkPad X21====<br />
*Ubuntu versions 6.06, 6.10, 7.04 (Dapper, Edgy, Feisty)<br />
<br />
Because the X21 does not have room for a CDROM, one must plug it into the dock to perform a CD based install. Early versions of the dock are known to have USB problems, which in turn cause Linux installation issues.
