I have a one-wire device behind a Exar XR21B1411 USB UART that I need to access with an Arduino. I have the Arduino USB host shield and tried to use the cdc_XR21B1411 example from the Host Shield library 2.0 but had no success. It seems to me that I have to use the One-Wire protocoll over usb. Any hints or ideas on how to use this? Is there a library available that can send low-level one-wire commands over the USB host shield? It is not possible to detach the One-Wire sensor form the UART, unfortunately.
Any idea is appreciated, I have to get this working, but since few days no success.
