So I've got this NEC USB card
02:02.0 USB Controller: NEC Corporation USB (rev 41) (prog-if 10 [OHCI])
Subsystem: Orange Micro Root Hub
Flags: bus master, medium devsel, latency 8, IRQ 64

02:02.1 USB Controller: NEC Corporation USB (rev 41) (prog-if 10 [OHCI])
Subsystem: Orange Micro Root Hub
Flags: bus master, medium devsel, latency 8, IRQ 65
Memory at c00000080fe05000 (32-bit, non-prefetchable) [size=4K]
Capabilities: [40] Power Management version 2
02:02.2 USB Controller: NEC Corporation USB 2.0 (rev 02) (prog-if 20 [EHCI])
Subsystem: Orange Micro Root hub
Flags: bus master, medium devsel, latency 68, IRQ 65
Memory at c00000080fe06000 (32-bit, non-prefetchable) [size=256]
Capabilities: [40] Power Management version 2
Apparently it's USB 2.0 capable, but I can't seem to get that to work. In
fact, if I allow the ehci_hcd driver to be loaded, regular USB 1.1 devices
fail to work at all (I don't have a USB 2.0 device to test with
unfortunately). I've attached the relevant parts of my system log. It looks
like something bad is happening with the EHCI/OCHI interrupt handling, since
I see "IRQ 64 nobody cared" and /proc/interrupts indicates that one of the
interrupts (I guess one of the OHCI ports) is triggering out of control:
64: 176477117 0 SN hub ohci_hcd
65: 0 0 SN hub ehci_hcd, ohci_hcd
Any ideas? Does it matter which driver I load first, ehci or ohci?
Thanks,
Jesse
