I have a Zketech EBC-A40L which I’ve used without issues on my windows 10 laptop.
Today I tried to use it again, but when I opened EB tester I couldn’t see any COM port to be selected. The USB to serial is visible in device manager (Com 10). I’ve tried uninstalling and reinstalling both the software and the driver without success.
I tried with another laptop but it is Windows 11 and it doesn’t seem to be supported (exclamation mark near the usb to serial in device manager).
Any ideas?
