SuSE Linux: Version 7.2
This article refers to an older version of SuSE Linux. Therefore some of the informations given in this article may be outdated or the article may contain stale links.

Symptom

During the installation the hardware detection fails with the following message:
"Starting hardware detection
> usb.3: read info"

Cause

The USB hub included on your mainboard wasn't assigned an irq.

Solution

Please activate the interrupt assignment in your BIOS. If you're using an Award BIOS, this option is called "<Assign IRQ For USB>" in the menu "<PNP/PCI CONFIGURATION>". Please make sure that this value is 'enabled'.

The usage of the boot parameter 'hwprobe=-usb' will prevent USB to be probed during boot time and the installation will keep up proceeding.
This parameter has to be typed in at the boot prompt. This should look like this:

boot:linux hwprobe=-usb
