I'm afraid it shows only that the controller was working initially.

No, it's not related.  Or not directly, anyhow.

If all you care about is getting the thing to work, you can try simply
removing the statements under the "case UHCI_RUNNING:" label in
uhci_hcd.c:hc_state_transitions() -- just leave the "break" statement.  Of
course, that won't get you any nearer toward understanding what was wrong
in the first place.  Also it will prevent your computer from entering 
certain low-power-utilization modes.

Have you been able to get the source code for the Knoppix kernel that 
worked successfully?  Does comparison with the Fedora souce reveal 
anything?
