Default Xilinx Impact USB speed problem

Starting with ISE Webpack 8.2, I have to manually set the speed of the USB
port to 3 MHz every time I start Impact, because with 6 MHz the write
process is ignored most of the time and the old configuration is still
active. How can I preset 3 MHz? Looks like it is not stored in the Impact
project file.

Or any other ideas why 6 MHz doesn't work on my computer?

I've solved the problem for me: When hitting the "PROG" button or turning
power off and on before accessing the board, looks like it works all the
time, even with 6 MHz.
