I had successfully running VB based software for ADC 100 on Windows 2000 through parallel port LPT1. Recently I have purchased ADC 100 with USB adaptor and tried running same VB software but had messages "adc opened" and "pico.sys not found" while before with LPT1 port I had following messages on excel opening screen "ADC opened", "LPT1, Use adapter", "pico.sys V1.5" and "55803samples/sec"
I have downloaded all necessary data form CD ROM (r.29). For your information USB port talking to my PC and I can get both channels on PicoScope. I suspect that I have to get VB to look for picopp.sys but not sure how or it is only part of the problem.
