This is a fork of CH55x-USB-Blaster firmware by VladimirDuan that runs on a cheap clone Altera USB Blaster I bought on Amazon. On the outside it says "Rev. c" and it uses a CH552G chip. It works correctly in Linux and Windows with my limited testing, no special drivers required.
Compile with ch554_sdcc SDK.
