    USB2 Enabled?


    Installed a new USB2 PCI card, and I can see the attached drives (yay!), however, the access seems to be a bit slow, which makes me wonder if they're being accessed as 1.1 devices instead of as USB2. Is there a way I can make sure that USB2 drivers have been loaded, and that the drives are being accessed at full USB2 speed?

    Thanks,
    Ewan

    Well, yes, that tells me the card is there. But it doesn't tell me if the drives are being accessed through usb2 rather than 1.1. Based on the transfer speed I'm thinking that there is something I need to load besides the normal usb-uhci that isn't coming up by default.

    A little research makes me think I need ehci-hcd, but I'd appreciate it if someone could confirm that.

    Thanks,
