Try shorting those pins WHILE the USB is plugged in. It "should" start the device wizard and the driver will be located in the ATMEL\FLIP\usb folder.
Hi spcomputing:
Yes I did short those pins WHILE the USB is plugged in(Shorting-->device unplugged, unshorting-->device plugged). But the device wizard did not start since the computer think it is still a Arduino Uno instead of other device. I tried "upgrade driver" and force it to select flip's driver, but computer refused to install.
I feel like the DFU mode is not activated after shorting.
Any thoughts?
