Hi, I have used a USB-TC device before and didn't have any trouble. Recently, while running an experiment, the computer gave me an error and said it didnt recognize the usb connection to the USB-TC device anymore. Tried many times to run instacal on it, but it simply didn't even detect it. Found another USB-TC in my lab and connected it successfully, only to fail after half an hour of running and now instacal can see it, but calibration fails, configuration gets hung up, unusable. I installed instacal in another computer that had never had it installed to test if my lab computer is creating an issue. Got same results for both devices. Is there a way to troubleshoot/repair/reset these devices, please?
