It finally worked
My D- and D+ were inverted.

The drivers i got from my CCS
"C:\Arquivos de programas\PICC\Drivers" - Default

I got a doubt, what is the correct speed in Hiperterminal? I'm working at 115200, but i'm not sure if is the best one.

thanks again

sorry somasundari, you must give the inf all the times you change from usb port, at least you could set windows to find the driver, it will get the previous installed inf. from system.

Re: Easy PIC USB CDC

The problem with the cdc driver:
When you insert the usb, you will receive something like : No driver.
Go to Device Manager,you will see your usb without driver in the list.
Go to Properties,Details - and from property -select Hardware Ids
You will see : USB\VID_0461&PID_0033 ( or other value)
go to your hex directory, open the mchpcdc.inf file, go down some rows to :
[DeviceList]
%DESCRIPTION%=DriverInstall, USB\VID_04D8&PID_000A
Replace the VID_04d8 end pid_000a with your value from device manager.Then save the inf. file, go to update driver and go to your modified mchpcdc.inf
You will receive from windows something like driver not verified - continue....and 100 ok.
