ESP32-C3 USB CDC

Hello.
I'm use USB CDC in my project on ESP32-C3, as "serial device".
Had to add new value of .tx_mode in vfs_serial_usb_jtag.c, which enable to transmit array wihtout
line ending symbol.
USB host on PC, Windows 7, libusbK driver (USB JTAG/serial debug interface). Virtual serial port may
transmit only 7-bit symbols. To transmit bytes i need to convert it to "text-hex" values (2 symbols).
This doubling traffic.
Who reseting most significant bit ? ESP32-C3 internal driver or Windows driver?
