Question asked by durgesh saxena on Jun 1, 2018

I'm using STM32F070RBT USB CDC device to communicate with PC. CDC channel is working fine except one issue. Looks like current channel has 63 character limit. i send 500 characters but i receive only 63 in buffer but  buffer size in HAL is 1000. can anyone tell me whats going on?
