I am evaluating the ADUM4160 USB Isolator. The primary function for which this part is intended is working as expected. However, when I use this device with some USB devices connected to a PC operating on Windows 7 I am not able to communicate. I understand that this device only operates at full speed but this device is 2.0 compliant so my expectation that connection should be established. It would just run slower. Is there anything with respect to the 4160 hardware implementation that would cause this issue or is this an issue with the specific device's driver and / or Windows 7?
