Specified port is unknown
Posted on 2006-11-21
We are using xp pro sp2 and have a brother hl-2030 printer connected via a usb connection. This was working OK, but suddenly the printing stopped working.
We romoved all of the printer drivers and tried to re install, but the hardware is detected and the drivers seem to install, but we keep getting an error message saying there was a problem installing the hardware as the "specified port is unknown".
We have tried a differnet printer, and exactly the same thing happens.
We have removed the USB ports from device manager and re installed them again, but still no joy.
We have tried installing the drivers manually, but the USB port option is not there.
Does anyone have any ideas.
