Hi !
Love your windows driver for Usbtiny ! Great work !
But how hard would it be to add a FTDI 232 chip to the known Usbtiny circuit ?
Usbtiny with FT232 chip ?

Could you post a link to the circuit or product you're thinking about please?
We have the TinyUSB library, and several different USB-to-Serial converters.

FTDI chip cost like 1-2 €

Re: Usbtiny with FT232 chip ?
I think they meant which Adafruit product you're talking about.
I'm suspecting usbTinyISP (which uses a SW bit-banged USB rather than an FTDI chip, but...
I don't think there is much point to having an updated dedicated programmer. Pretty much any Arduino-compatible board running the "Arduino as ISP" sketch will do as well, and many will end up cheaper than the original usbTinyISP (and easier to upgrade firmware.) And there are competing products like the Bus Pirate that you did show, plus more reasonably priced programmers (like the "MPLAB SNAP") from Microchip themselves, that are much more capable.
the USBTinyISP was an important product in its day, but that day is past.

i mean how hard can it get ? after all it makes live so much easeir .. i got never any problems either in win95 or win 10 to find my bus pirate.. can't understand why not many more products use FTDI chip for usb interactions

Well, there was "FTDIgate"...can't understand why not many more products use FTDI chip
The FT232RL used on the Bus Pirate and pre-Uno Arduinos was/is quite expensive, compared to many alternative chips. Even FTDI has newer chips that are half the price.
Chips with "Native USB" hardware are generally a better idea (faster, for one thing. Fewer parts.)
You still haven't explained exactly which product you're talking about, and why there should be a newer version (at all.)

and thanks for the heads up .. never noticed FTDI gate .. seems to me checking chips will be a routine if i get hold on these suckersi got never any problems either in win95 or win 10 to find my bus pirate..
