OK, so I installed on my wife’s laptop, using the instructions found here. Only change to that, was I used the driver you provided above. Worked fine with existing cable.
Went back to the original computer. I uninstalled lightburn. Ran the driver uninstall for BOTH the CH40 drivers, one you mentioned above, and the original driver in that previous thread… Rebooted, then followed procedure above, except using the driver you recommended. Same issue. “Waiting for connection”. If I change the port in device manager, in lightburn, I get a message about “being in use”.
Seems like it is surely a driver issue. I tried uninstalling the drivers using their exe installers. Couldn’t figure out how to uninstall the FTDI driver that Lightburn installs. I also tried uninstalling the driver through device manager. No real changes.
Open to any further suggestions
