Hi, I have also bought a HL cable, unfortunately I do not get it to work.
When I plugged it in for the first time, Windows Vista's hardware installation assistant started and asked for drivers.
Unfortunately I did not have the CD at hand, so the assistant quit the installation. Whenever I plug in the cable now, nothing happens.
No "new USB device"-sound and no activity. I tried to install the drivers manually, but no success - still no reaction when the cable is plugged in. I tried to search for new PnP Hardware in the device manager - no success. Also when I try to manually install new legacy-hardware and try to install from the driver disk, no devices are found.
Could anybody help me how to solve this? I am really stuck Help is appreciated, as I need the serial port urgently Greetings, Bexman. View a Printable Version. Lost Password? Attached Files ch34rser.
