The cable is branded "Ugreen." I've had difficulties with USB to RS232 adapters in the past, which is why I bought it from the ADTPro website. I figured that it would be more likely to work straight away.
When I stare at device manager and pull out the cable. nothing happens. If I scan for hardware changes, the system still sees "unknown device" and "base system device" and tries again to find drivers for them. Device manager is showing an installed USB to serial adapter, but these others won't go away. On a venture to the grocery store today, I stopped in at a Radioshack which was having a liquidation sale. I bought their "Gigaware" USB to serial cable for a decent discount at $20. As I understand it, this one uses a Prolific chipset which can occasionally be troublesome.. Thankfully, there appear to be drivers for it specifically for Windows 7. I'll give it a shot and report back. Thanks for your're assistance! Joe Giliberti
