HID-class serial communication for AVRs using V-USB
After a lot of optimising for size and writing chunks of the code in assembly and removing the class, I managed to shrink HIDSerial down to a compile size of 2046 bytes flash and 97 bytes ram including routines to use the hardware UART module on the ATTiny2313. It fits with 2 bytes to spare and works :D
I needed a USB-USART (TxD, RxD, Clk) converter for a project I am working on and this has made that possible.
Hi ray I think you used a different protocol.
I tried this app and it didn't work

I'm trying to use python hidapi lib to communicate with the board. I can read, but writing is not working. Seems the board receives nothing.
Edit: also tried: https://github.com/todbot/hidapitester with same result. Reading is possible, writing is not.
