PIC32 USB CDC Error

[SpeedPIC32]

Hello
another error has occurred with the USB interface.
Unfortunately, this is an old error that has occurred several times before. Old projects are once again not being compiled.
last discussed in Dec 2020
after that it still worked.
can the last update be to blame?

greetings SpeedPic32

The file CAL\PIC32BIT\PIC32BIT_CAL_USB_Serial.c doesn't work at all! Version 2
Missing ;
After that more errors...
Seems to be a badly copied and modiefied version of PIC16BIT_CAL_USB_Serial.c ? At least it says so in the description part of the file.

Hello


Please check USB CDC
no longer works since the last update.
I can't even get the original examples like " ADC 9 Click BEN_1 " which I have freshly loaded here to work.
Would be nice if someone could test this.

Thank you very much
