Laptop computer that connects to a Printer (it is actually a vinyl cutter / signwriter) via a USB socket that then detects it as a "usb to serial" device, the software that talks to it must use either com 1 or 2. The problem is that the USB's come up as coms 3 to 11, This used to work on this laptop but has stopped and other people have played with it.
There are NO serial ports on the laptop and the bios is set to none. I did find a regkey that refered to the ports and when i deleted it, it then redetected the port as the next number eg 12.
What i want to do is reset all the USB data to as it is from new when it will detect something as though it was never there before. i have tried uninstalling the hub and then letting it redetect it and the numbers then just grew.
Any suggestions before i just blow this thing away and do a fresh install of XP.
