I have been struggling to set up a USB->Serial communication cable so I can talk to an electric car controller. The problem is that on my XPpro laptop, there was no COM port folder, and the driver for the cable doesn't seem to install.

I found a way to create a COM folder under Device manager:
- click 'Action' tab
- 'add legacy hardware', next
- radio click 'install manually'
- select 'PORTS'

this did create a COM4, but it shows conflicting resources and not functioning correctly.

Install of the serial driver doesn't show up, so I cannot configure to a functional COM port, so I cannot configure Putty to run (instead of the old HyperTerm I used to use on an older machine).

The question boils down to how to create a functional COM port in XP pro ?!

making progress.... I finally found a useful driver update and instructions! http://www.usb-drivers.org/gigaware-usb-to-serial-driver.html has a link to a download for the gigware usb-serial cable. The process I followed was:

- dowloaded the driver
- went to device manager
- 'uninstalled' the non-functional COM4 port I had created
- plugged in the USB-serial cable, and the computer detected and created a 'other device' with a questionmark
- right-click new device, click 'update driver', browse to location of downloaded driver

system installed driver, and created a functional USB serial port COM4 all on its own!

now I have to go see if it will talk to thru Putty to my car controller.....
