[weewx-user] Re: Selection of USB/RS232 device to RPI. To control WMR 928
An rs232 -> usb which uses an FTDI chip works the best as it usually contains a serial number which is useful in setting up a udev rule. Mwall has posted a good guide to creating a rule for this purpose. I had been using a converter with pl2303 chip but started having problems with it switching ttyUSB on me.
