W7 error = Device not be found

Well OK,
the manual is incomplete, it is impossible to install an unsigned driver before
have disabled driver signing: bcdedit / set ON nointegritychecks

Restart the PC and install the unsigned driver (Win_xp_W7 I did not pass the 64-bit).

After install: bcdedit / set nointegritychecks OFF.

the graphical interface is well designed, remains a constant noise.

Must see to use.
