I have a PIC 32 USBCDC problem :roll:

[SpeedPIC32]

The compilation runs without errors

The simulation is also running

when I have transferred the hexcode the program hangs in the initialisation. When I deactivate the initialisation the PIC enters the blinking loop. Windos always indicates that the USB device is unknown

urgently need help

Hello,

I think your project clock speed of 80MHz may be the cause of the problem. You might need to adjust your clock settings to get a rate of 48MHz to allow the USB to function.

this may help.

Unfortunately this is not the problem.
Quartz frequency is 8Mhz /2=4 x 20 =80MHz 'clock for PIC / Prim Osz.
Quartz frequency is 8Mhz /2=4 x 24 =96MHz / 2 =48MHz for USB / Prim Osz
