Where's the driver for the CC2531 USB dongle? The documentation states to point ot the usb_cdc_driver_ccxxxx.inf. However only the 2511 and 2510 version seem to be available int the USB Firmware Library with software examples Rev C. The PID is different 0x16A8 (CC2531 rf modem example) and so the CC2511 driver will not work as it states 0x16A4 in the .inf. I previously loaded the dongle with the RF_modem.hex file from the CC2531 directory
