Hi, As suggested in the message below, I have tried to use an EMTEC S830 with the treza's patch. I did not succed but I had some encouraging results, so If someone would to continue or give me an advice, this is what I did : First, I found vendor and device ID with lsusb and the confirmations that it use STK7700D Bus 005 Device 005: ID 1164:1e8c YUAN High-Tech Development Co., Ltd Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x1164 YUAN High-Tech Development Co., Ltd idProduct 0x1e8c bcdDevice 1.00 iManufacturer 1 YUANRD iProduct 2 STK7700D iSerial 3 0000000001 bNumConfigurations 1 ...

The scanner show some good signal (from 20% to 100%) on several frequencies but it never lock nothing. I could verify that the hardware was really sending signal by removing the antena (the signal became 1% to 2%) I tried to reuse frequencies from another DVB for reading the multiplex with vlc but not much : vlc -vvv --color dvb:// :dvb-adapter=0 :dvb-frequency=474000000 [...] [00000292] dvb access debug: Opening device /dev/dvb/adapter0/frontend0 [00000292] dvb access debug: Frontend Info: [00000292] dvb access debug: name = DiBcom 7000PC [00000292] dvb access debug: type = OFDM (DVB-T) [00000292] dvb access debug: frequency_min = 44250000 (kHz) [00000292] dvb access debug: frequency_max = 867250000 (kHz) [00000292] dvb access debug: frequency_stepsize = 62500 [00000292] dvb access debug: frequency_tolerance = 0 [00000292] dvb access debug: symbol_rate_min = 0 (kHz) [00000292] dvb access debug: symbol_rate_max = 0 (kHz) [00000292] dvb access debug: symbol_rate_tolerance (ppm) = 0 [00000292] dvb access debug: notifier_delay (ms) = 0 [00000292] dvb access debug: Frontend Info capability list: [00000292] dvb access debug: inversion auto [00000292] dvb access debug: forward error correction 1/2 [00000292] dvb access debug: forward error correction 2/3 [00000292] dvb access debug: forward error correction 3/4 [00000292] dvb access debug: forward error correction 5/6 [00000292] dvb access debug: forward error correction 7/8 [00000292] dvb access debug: forward error correction auto [00000292] dvb access debug: card can do QPSK [00000292] dvb access debug: card can do QAM 16 [00000292] dvb access debug: card can do QAM 64 [00000292] dvb access debug: card can do QAM auto [00000292] dvb access debug: transmission mode auto [00000292] dvb access debug: guard interval mode auto [00000292] dvb access debug: hierarchy mode auto [00000292] dvb access debug: card can recover from a cable unplug [00000292] dvb access debug: End of capability list [00000292] dvb access debug: trying to tune the frontend...
