I burned DBSRX usrp2 firmware image (burn_dbsrx_eeprom.bin) as suggested, but then only F LED turned on and find_usrps command says: No USRP2 found which was not the case initially.
I also tried burning Raw ethernet FPGA image and Raw ethernet, no WBX or XCVR image on the SD card. LEDs D and F lights up but still find_usrps gives No USRP2 found.
(While burning all of those firmware and fpga images using (both usrp2_card_burner_gui.py and dd.exe), I received an error - error 87 the parameter is incorrect)
