(In #2401) In fact this is a duplicate of bug #5. From the syslog it tells that a UHCI and an EHCI controller were found, but that both could not be used because they have an invalid IRQ assignment (or none at all probably). As this should automatically resolve as soon as bug/enhancement #5 is done, it shouldn't really be necessary to keep this bug open.

(In #2620) The cause can be seen in the first screenshot at the top. Both the UHCI and EHCI controllers present have invalid IRQ assignments, which means that the BIOS didn't initialize interrupt routing for them. That means, this is in fact a duplicate of bug #5. If it works when you have a IDE disk connected this probably causes the BIOS to do some additional setup that it doesn't do when that's not the case. Maybe there are some USB legacy settings in the BIOS that you can try changing, otherwise there's not much you can currently do.
