I have just received a new Laptop (Dell MD3800) and am encountering difficulty in getting the new USB Driver to work. Ironically, if I use a port replicator, which has a 1:4 USB hub that has its own supply, the drivers work perfectly. So, I just wanted everyone to know that this is something that I am working on but I wanted everyone to know that new PCs may have some sensitivities that were not present in older Win 7/64-bit machines.
