I bought a picoscope 5204 years ago.
I have had a problem with it since i bought it.
It disconnects the device from the computer time and again.
suddenly out of nowhere it disconnects, and the only way to reset is to pull the power plug.
I have tried different computers. same problem, even with the "Picoscope.exe*32 set to high priority:
windows XP or 7 in 32bit or 64bit doesn't seem to help
i have tried a benchtop power supply to exclude its own power supply. still same problem
i have of course tried the different software updates that has been developed.
It seems that nothing really helps.
Do you have an idea of what the problem could be?
