Folks, I've developed an open-source python library for RFID, called RFIDIOt (http://rfidiot.org), which works with ACG serial RFID readers. I've just acquired the USB version of the reader and wanted to add support for it, but it isn't immediately recognised by the usbserial driver and I wondered if anyone had any ideas on how to get it fired up?
