Hello guys
i need some help with the 18F4550 and W7 USB (CDC serial port).

I wrote several PC & PDS applications exchanging data beetween the PC and the 18F4550 via USB CDC virtual port .
All of them are properly working on WinXP and W7 32bits.
No one is working on W7 x64 and I'm not able to identify where the problem is.

The 4550 connects W7x64, it is recognized, virtual port is created without any error (Microchip driver 5.1.2600 the same version of 32bits is installed and initialized) but when i try to communicate with the pic no answer, repeat this appens only on W7 64bits.
The Serial Comm program of PDS has the same problem (unable to connect. The serial port is being used ... not sure error 10? no error is higligthed by Control Panel/System) but different communication programs (ex. Termite) open and properly communicate with the pic. This appens only on W7 x64.
Any help how to investigate?
Thanks, Tony,i2tzk
