Has anybody come up with a driverless USB substitute for rs232 avr<->PC communication?
I just figured I'd ask here before abandoning the idea.
I was looking into possibly using a usb-hid joystick class as a solution that would require no driver installation. From what I have read, this would work for passing data from the avr to the PC, but there is no driverless usb output besides numlock, scrolllock and caps lock leds. As far as I can tell all other outputs require v-usb win32 for windows. The only other possibility was maybe a mass storage device, but that becomes awkward to use for sending a simple stream data command.
I have several data acquisition devices I make for customers. USB connectivity is the only choice they have, so I have been providing rs232 and then using an adapter such as an FTDI or Keyspan. I keep doing this because then the (signed) drivers on the PC side are provided by the adapter manufacturer. Sometimes people have to try a few adapters before they get one working. What people really want is to just plug in a USB cable and be done.
For any thoughts, Thanks in advance! :D
