Zero Length Packet necessary? (USB STM32F407 VCP bare metal)
I thought if I transfer e.g. 64 bytes I can load pktcnt with a value of 2.One for 64 bytes, second for ZLP?Or do I have to send it manually after IN transfer complete interrupt?

i am currently using the serial pins and a FTDI chip to communicate with a PC. I want to know if there is a way to use the on board mini USB port or the OTG port to communicate with the PC.
USB STM32F407 VCP Bidirectional communication bare metal?
I'm sending a continuous data stream from uC to PC via VCP which is implemented as CDC. During stream every responded IN token for EP1 generates DIEPINT_XFRC, so I'm seeing interrupts:DIEPINT_XFRCDIEPINT_XFRCDIEPINT_XFRC...Now I send something to uC ...
