CH32X035 : use CDC to PC trough USB , both direction working ?

[trimarco232]

Hi all ,
Some people have managed to print from the chip to the PC (arduino monitor , for example).
But I did not find any code allowing to send CDC datas from the PC to the chip ?
Is there any definitive reason for this , or am I missing something ? thank you

I tried to support USB CDC on CH32X035 and created PR in TinyUSB. But it doesn't work properly now by some bugs.
