I bought a PCI card with 5 usb 2.0 ports before getting my Sony HD5 and now I find that whenever I plug it in I get an error message "Device not recognised". I have to admit it is a cheap card. So I'm stuck with the old usb 1.1 ports but transfers take forever and the device gets very hot during transfers. Have you had similar problems? Anyone can recommend a PCI card to add usb 2.0 ports? Thanks.
