This sounds like a question for Orange Micro support.

The card will work as 2 USB 1.1 OHCI controllers without any additional software, the normal USB stack has no problem with these. The USB stack does not support the USB 2.0 EHCI controller, so to get high speed transfers you need Orange's driver.

If you're not getting high speed transfers either the Orange driver is not working and you need to talk to Orange support or you don't have a USB 2.0 hard drive.

I would not be surprised if it showed up as only one device in Apple System Profiler, that usually does not show OHCI devices, so all you would be seeing is the EHCI device. IORegistryExplorer should give you more information. -- Barry Twycross email@hidden --- USB, it's not a Dyslexic BUS.
