Radio Shack driver-serial to usb cable
I just bought Radio Shack's "6-ft USB to Serial Cable", model #26-183, to use on my new HP m8120n with Vista. I tried for a long time to load the driver, and just about gave up, but persistence finally paid off. When I installed the driver first off of the CD, it seemed to do it, but when I connected the Radio Shack cable to my USB port as the 2nd step, Vista wouldn't find the driver, even when I pointed it to the installation disk. I tried over and over again, and I figured it just wouldn't work with Vista and I would have to return it. I also had tried the XP/SP2 compatibility mode, running as administrator, with no luck. I finally got it to run by messing around with the COM port numbers involved. On my device being hooked up, the COM port setting was COM3, and it wouldn't allow me to change the number. In Device Manager, I found that the built-in phone modem was using COM3. I changed the modem to a different number - COM6, and then changed the R.S. adapter (which was listed all the time in Device Manager, but just not working properly) to use COM3 (instead of some other number that was assigned to it). Now that the R.S. adapter in Device Manager had its COM port number matching the COM port number in the software program being used to control the new device being hooked up by the serial to USB adapter, it worked.
