Work related but today I ran across a problem with a datalogging current clamp, the device in question has a USB port on it which is implemented using an FTDI chip (I think FT232).
Plugging it into a freshly built Windows 7 laptop and installing the drivers from disk allows the clamp to be recognised and work with the supplied application but after a reboot, power down or removal/reinsertion of the device Windows pops up a message 'USB Device Unrecognised' and after that no amount of effort will persuade it to work, trying to reinstall the drivers manually etc...
There is no problem with the Win 7 install or laptop hardware, it recognises USB HID, Mass storage etc. with no problems, but this data logger and several others of exactly the same model all exhibit this problem on several laptops.
Could it be a symptom of FTDIGate or am I being overly suspicious?
