I just bought a nice new USB 2.0 card for my computer, but dsl only recognizes it as USB 1.1! Ive downloaded USBview from the mydsl icon, and it still does it. btw, I have tried both Live CD and HD installations. Any help will be appreciated.

That may be because the PCI bus only operates at either 66 (pci 2.0) or 133 (PCI 3.0) mb/s (that's megabits, not megabytes, folks) and not the 480 mb/s that the USB 2.0 or 2.1 spec calls for. A true USB 2.0 or 2.1 bus has to link directly to the northbridge of your mobo to accomplish these speeds.

Long story short, you can't get real usb 2.x speeds off of a pci bus.
