When I got my Evo, one of the first things was soft installation and attempt to make it working. With supplied Gembird USB-DB9 adaptor cable all three PCs were doing very strange things (Acer tablet, desk top Compaq and custom one), after attempt to replace USB driver with supplied one all three went to reboot. Thought both desk top were working good with direct connection to com port (DB-9).
Took another manufacture adaptor and, BINGO... all came back to normal operation (had to reinstall original usb driver on all three XP PCs).
No problem with upload/download since that.
Contacted SDS in regards to replace that cable but answer was... , unfortunately 'silent'.
All what I heard so far from people having problem with Vision soft installation and running the program mainly related to usb port.
Just try first DB-9 connection to computer com port (if you have one and/or have both desk top and laptop PCs) if it works, than kick out that gembird on garbage and get another adaptor. In Canada they are available at 35-45.00 CAD just about anywhere.

Cheers,
