I obtained a PCI to USB2.0 adapter: 09:02.0 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 61) 09:02.1 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 61) 09:02.2 USB Controller: VIA Technologies, Inc. USB 2.0 (rev 63) 09:02.3 FireWire (IEEE 1394): VIA Technologies, Inc. VT6306/7/8 [Fire II(M)] IEEE 1394 OHCI Controller (rev 46) and plugged the Edgeport unit into that. Still the exact same problem, so it doesn't seem to be a hub issue, correct? I tried unloading ehci_hcd, then modprobe-ing io_ti, but with the same result (-EINVAL). Anything else I could try? -- Philip J.
