Running SS 3.8 under Win XP with USBi drivers, it all works as expected.
On my laptop, running Win 7 X64, with the x64 CyUSB driver installed from the AnalogDevices directory, it doesnt.
When I plug the device in, I first get the USBi icon on the hardware screen changing state to light orange, and the device appears functional. I can turn the device power on/off for example.
When I hit F7, it says "active downloaded" with the usual green bar .. then a little while later, "comms failed" .. but the bar stays green. I suspect the "active downloaded" as the device never achieves a functional signal path.
The schematic is one that was developed without problem on my desktop, under XP, so no issues there.
Did I miss something obvious?
