I am running VISTA Home and recently installed a Serial to USB converter (Keyspan). Unfortunately, the comm port is set to 28, which is too high. The only available ports, via keyspan advanced properties in device manager, are 28-31. I need to assign the device to a comm port below 9. Any advice?

Bit more info might be helpful...ie make , model/serialnumber of the keyspan etc...Any paticular reason why you need it to have a comm port below 9 ?Why not just let the converter assing a port as be ? Is there a problem when the cnverter self assigns ? Is there an error message when it self assigns.? Please let us know. THese miht sound trivial, but might also help in sotrtng your problem

The keyspan model is USA-19HS. I don't think the software application I am running is able to communicate to ports above 9. No error message occurs.

The biosensor is a proprietary sensor and details are limited. It's basically a homemade galvanic skin response sensor. It communicates through a serial port. The keyspan converts the serial to a USB interface. Our proprietary software is built on VB6 and I don't think the control being used for comm port selection goes beyond 9, hence our problem. We have this system installed on 100's of VISTA machines but I am assuming the comm port selected for the keyspan device on those machines is below 10.

You can change comm port numbers in your device manager.I'm not at a vista pc at the mo. i will check when i get home but i think you go into device manger> advanced properties and you should find it in there.Like i said i'm not at my vista pc. I'm in work, with broken foot n all.

Also did you not get a driver cd with the usb adapter.
