Or else maybe you need to modprobe ohci-hcd. Hmm, this is weird. ehci_hcd is built in the kernel. uhci_hcd doesn't load properly: USB Universal Host Controller Interface driver v3.0 PCI: Fixing up device 0000:01:02.0 uhci_hcd 0000:01:02.0: no i/o regions available uhci_hcd 0000:01:02.0: init 0000:01:02.0 fail, -16 uhci_hcd: probe of 0000:01:02.0 failed with error -16 PCI: Fixing up device 0000:01:02.1 uhci_hcd 0000:01:02.1: no i/o regions available uhci_hcd 0000:01:02.1: init 0000:01:02.1 fail, -16 uhci_hcd: probe of 0000:01:02.1 failed with error -16 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) 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.
