Evidently there's something wrong with the UHCI controllers on that PCI device. I don't know enough about it to diagnose the problem; you should try posting these messages on a PCI mailing list or perhaps on LKML. > However, it looks like I have UHCI, not OHCI: > > # lspci > 00:00.0 FLASH memory: Broadcom Corporation Sentry5 Chipcommon I/O > Controller (rev 01) > 00:01.0 Ethernet controller: Broadcom Corporation Sentry5 Ethernet > Controller (rev 01) > 00:02.0 Network and computing encryption device: Broadcom Corporation > Sentry5 Crypto Accelerator (rev 01) > 00:03.0 USB Controller: Broadcom Corporation Sentry5 USB Controller (rev 01) That device (00:03.0) is OHCI. It must be on the motherboard; perhaps it's an internal-only USB controller or perhaps it isn't wired up to anything at all. > 00:04.0 MIPS: Broadcom Corporation Sentry5 PCI Bridge (rev 01) > 00:05.0 MIPS: Broadcom Corporation BCM3302 Sentry5 MIPS32 CPU (rev 01) > 00:06.0 RAM memory: Broadcom Corporation Sentry5 DDR/SDR RAM Controller > (rev 01) > 01:00.0 Host bridge: Broadcom Corporation BCM5365P Sentry5 Host Bridge > 01:02.0 USB Controller: VIA Technologies, Inc.

You should try to see if that OHCI controller has any accessible ports. If it does, you ought to be able to get your other USB devices to work with it.
