Both apparently exist, but the firmware is the same. The main difference registers in the firmwares dvb-usb-it9137-01.fw -->clk enable 0xd81a --> tuner_it91x_priv.h...set_it9137_template dvb-usb-it9135-01.fw -->clk enable 0xcfff --> tuner_it91x_priv.h...set_it9135_template dvb-usb-it9135-02.fw -->clk enable 0xcfff --> tuner_it91x_priv.h...set_it9135_template As far as It can tell all the latest firmwares are based on set_it9135_template. On the KWorld the second device is another it9137 and has an eeprom 24c02 fitted. So dropping the dvb-usb-it9137-01.fw firmware is fine.
