The real problem here is that USB does not define a standard interface for an RS-232 adapter. Proprietary drivers should never have been required for these. Same deal for Centronics printer adapters.
- userbinator 12y agoIt does, it's called CDC and there are plenty of other adapters that use it. Which is why I think the popularity of FTDI adapters is surprising in some ways.
- jhallenworld 12y agoVery interesting. I've been reading all about it: http://www.recursion.jp/avrcdc/driver.html http://www.recursion.jp/avrcdc/driver.html
- dfox 12y agoThe problem is that on Windows you still need .inf file with correct VID/PID (this is the case for eg. MCP2200). So for typical user there is not much of an difference between CDC and proprietary driver.
