Revision as of 13:21, 29 April 2009

An USB controller, that also contains an embedded DVB-T demodulator, produced by Tai-Hui and marketed under the brand name e3C Technologies.

This IC is used in many cheap DVB-T USB Sticks. Support is currently very experimental under Linux. (Only the combination with MXL5003S will work and only with 7 and 8 MHz channels.)

SinoVideo SV3420D-V02

Dvb-t-usb-sinovideo-sv3420d-v02-005.jpg

SinoVideo 3420D with MXL5003S (USB ID 18b4:1689). The PCB says SV3420D-V02.

Apparently produced by SinoVideo and sold under lots of different names.

As the windows driver CD is labeled SV3420A and timestamps are rather old, I suspect that the drivers didn't change since SV3420A. Equally the Linux driver should work for all revisions. Remote control part is recognized as HID device by the kernel.

Works with the driver from Antti's mercurial repository as described in [1]

SKU 08309 USB DVB-T Dongle

SKU 08309 USB DVB-T Dongle requires Firmware-File called EC168BDA.bin contained in Windows Driver TVGo_Genius.rar

WS-DVBTM2 Tevion USB-DVB-T

Cheap offer at Hofer (Aldi) in Austria. Has an EC168 and MXL5003s built in, which refers to the E3C reference design. Reffering to the link, the system only freezes after loading the dvb-usb-ec168.ko module under debian 5.0 unstable. All other modules load fine. Maybe other distros and/or hardware has better success. It's even impossible to load the firmware via dfu-ec168

DUTV007B USB TNT Basic LIGHT (GRTNTUSBV4)

DUTV007B.JPG

Same USB descriptors as SinoVideo 3420A-2, but with another PID... IR is detected directly by the hidraw driver (usbhid)

The PC-Basic v4 USB Stick contains following chips :

  • EC168 (USB 2.0 µ-controller, could be also a preprogrammed AVR or PIC)
  • Maxlinear MXL5003S Tuner [2]
  • EEPROM 24C02N I²C 0xA0 (256 Bytes) [3]

The windows driver also upload a 7109-bytes sized firmware (EC168BDA.bin) to get the device working...

Uploading Firmware to the device

  • EC168 Direct Firmware Upload tool based on libusb by Tanguy Pruvot : dfu-ec168

Something interresting with this device : We can patch USB ID and descriptors included in the firmware and/or device memory...
