Geniatech T230
A combined DVB-C, DVB-T and DVB-T2 USB 2.0 device from Geniatech. It is also known as MyGica T230 or Geniatech/elgato eyeTV T2 lite. It is supported since kernel 3.19. August T210v2 seem to be identical to MyGica T230.
Don't confuse this with Geniatech T220 or T220A that are the earlier models of the same product. The model number is printed on a sticker.\\ Don't confuse with the following model either, the Geniatech T230C, which looks the same but has different hardware (and requires different drivers).
The Geniatech PT360, also known as the D202, is likely to be the same device in just a different case, designed for USB OTG use with Android phones. With the correct adapter, it can be used on computers as can the T230 used with phones compatible with the PT360.

NOTE: This device needs I2C-Mux support in kernel or as kernel module (CONFIG_I2C_MUX).
Firmware
Firmware for both the demodulator and tuner are necessary. OpenELEC dvb-firmware collection includes firmwares for this device too.
- dvb-demod-si2168-b40-01.fw
- dvb-tuner-si2158-a20-01.fw
Place the 2 firmware files in /lib/firmware.

IR Remote Control
The supplied remote control is supported by the driver.
If the device is unable to initialize, you may want to prevent the IR from loading:
# cat /etc/modprobe.d/dvb_usb.conf options dvb-usb disable_rc_polling=1
A reboot is needed to take effect.
Known issues
Some problems with high bitrate DVB-C streams. Applies to certain DVB-C operators.
An Issue with firmware (TBD) can prevent the August T210v2 from working in this case use dvb-demod-si2168-02.fw instead.
