Hi all, Just finished read all the FAQs and postings regarding installation of V1.0.3. As indicated in the FAQ my UNO Rev 3 came as an unknow device. I followed the instructions to install the driver with success. Once I went to upload a test file, the UNO did not respond. After a replug, reboot etc the UNO now comes up as an "Unknown Device" under Universal Serial Bus controllers. I have tried several times now to delete the driver and re-install the driver manually however when I select UNO Rev 3, Windows 7 comes back saying it is incompatible. So I have given up for a bit and ask my fellow developers if there is something I have over looked.
