I picked up a cheapie Skype phone, which works well most of the time. When it doesn't, it's always the Human Interface Driver, which was "unable to load". I can eventually solve this by closing Skype + HID down, reinstalling, rebooting. Both then load properly on startup. Obviously this is not a great way to go. One thought is that the HID driver doesn't always load properly as a startup item. Anybody have any other ideas/ tips?
