This is happening even though Windows cannot recognise the device, so I can't stop Windows from auto installing from printers and devices because that option is only available for recognised devices. Then when I try to install the real drivers from the homepage (Downloaded on another PC and transferred on usb) Windows says it has determined that the best driver are already installed but the device is unknown in device manager. So, the pc is upstairs and I really cannot get downstairs to connect the thing direct to the roughter, my problem is when I plug my Wireless TP TL-WN422G dongle into the USB, Windows 7 automatically tries to install drivers for it and fails, I have a really odd problem with a build I've just completed, shame really because everything fired up nice but Windows 7 is giving me grief.
