Can I modify source code for the vitual com of nRF52833 USB CDC ACM in \examples\peripheral\usbd_cdc_acm?

[Tomlee]

Hi, 

   we are using D- and D+ in our nRf52833 board,    I want to use the CDC ACM USB class  as Virtual COM port.

  I found that there has a demo example in the \examples\peripheral\usbd_cdc_acm,  but it is only used for nRf52840,  

  Could I modify it for nRF52833?

I have already modified, it works well in nRF52388

but I have other question:

when I add usb cdc acm module files to ..\examples\dfu\dfu_nrf52833_xxAA_s113_7_0_1.emProject , and compile successful, then flash fw to EV board,  it shows messasge, as follow:

app_error_weak.c,  115, Mesh error 133 at 0x00000000 (:0)

Could you tell me why it happens , please?
