Fix Windows CI build

For some reason, macOS have issues with USB CDC,
surprisingly, CH340G convertor works just fine.
But FTDI and Bouffalo's USB CDC didn't worked.
Basically, without writing anything, we don't receive
response from board. This was fixed by adding drain
after writing BOUFALLOLABRESET handshake + adding
drains after every commmand write. Also, for some reason,
in USB CDC, the size of USB payload is limited, else
it will fail.
