I have an NEC-based 'UP215-N101' USB 2.0 PCI card which can apparently
appear as a device under ohci-hcd or ehci-hcd, depending on which one
is loaded.  If both modules are loaded, the device doesn't seem to
work, as it is detected by both

USB 2.0 controllers are supposed to be detected by both EHCI and either OHCI or UHCI, since they support both interfaces. EHCI is only used for USB 2.0 high-speed devices and OHCI or UHCI is used for other devices.

If the controller's not working, the problem will be something else..
