I have an ADC-20 connected via USB. It was working properly yesterday, but this morning I couldn't get it working.
Windows recognises the device - it appears as 'Pico High Resolution Data Logger' under Device Manager.
However Pico can't find it, and requests that I unplug and replug it.
I've tried it on two different computers (both WinXP), with both 5.20.6 and
It was bought mid last year from RS, and is serial number QJY39/43.
