Your 3223 scope was great, but now it no longer works. I may have had a ground fault glitch or something??? Microsoft windows opens a little balloon stating that it found new hardware as soon as I plug in the USB cable. The red light comes on in the front of the picoscope box. Then when I click on the shortcut and open the software, it says that it found no device connected.
Are there any diagnostics I can do to determine what the problem is?
