USB devices have a vendor/product ID that is used for driver selection. The ones for the FTDI and ch340 are different:

If you want existing drivers to "just work" with your clone device[1] then you need to return a vendor and product id it already recognizes. Lying to a computer does not make you a counterfeiter (and copying responses verbatim for interoperability purposes is pretty strongly protected, see e.g. Sega v. Accolade) [1]: After all the whole point of making an FTDI clone instead of just implementing the standard USB communications device class was to get Windows support before Windows 10 introduced support for serial via CDC out-of-the-box.
