I recently aquired an Itronix ix250 GoBook laptop (c. 2001), that seems to have a problem with Hub 2 Port 2.

Problems:

The message "hub 1-2:1.0 Cannot enable port 2. Maybe the USB cable is bad?" is printed in the console (CTRL+ALT+F1) approximately once every half second.

The message appears no matter what is plugged into the USB port and it appears if nothing is plugged in the USB port...in short, it just about always appears.

This message appears so constantly as to interfere with the use of the console.

When shutting down the laptop, it hangs indefinitely, constantly printing this message...the computer only fully sends the "halt" and shuts down if I plug in a USB device, such as a USB mouse.
Tests:
I tested an assortment of USB devices with the single USB 1.1 port on this machine and could not find any problem with their operation.

I have tested this laptop with Debian Etch, SUSE 10.2. The error appeared in all three installations.

I have gave GRUB the "acpi=off" option. The error still appeared.

Running "$ rmmod uhci_hcd" made the error message disapear and shutdown no longer hung. Unfortunately, this also temporarily turned off USB, so that I could no longer use USB devices with this computer.

I installed Debian Sarge, to see if I would have better luck with the 2.4.x kernel. The still error appeared. During startup, Sarge decided to disable Hub 2 Port 2. The USB port, PCMCIA port, and PS/2 ports all appeared to still function, even though this was disabled, which leads me to suspect that the USB port is not located at Hub 2 Port 2.

I looked all through the BIOS and could find no options related to USB.

Does anyone know what is the source of this error. How can I determine what piece of hardware is actually located at Hub 2 Port 2? I have run "$ usbview", "$ hwinfo", and "$ lspci -v" in search of this answer, but I couldn't make sense of the information in relation to this identification format: Hub #, Port #; to determine where things were located.

Any help greatly appreciated.
