I would like to connect to an AD with /SC, CLK, DO, and ground via usb. This is currently working with the serial (printer) port.
When I read I find that PL-2303 converter is needed (haven't looked at datasheet yet) but some or all of these are incompatible with Linux. I have found that a Nokia cable can be fiddled to go usb 2 serial (9 pin) and am contemplating that direction.
I have familiarity with tcp and understand that this is how usb communicates. Can someone who has worked with usb-2-serial cables advise me?
