Support for USB 1.1 and 2.0 DVB-T devices based on reference designs made by
DiBcom (http://www.dibcom.fr) and C&E.
Devices supported by this driver:
TwinhanDTV USB-Ter (VP7041)
TwinhanDTV Magic Box (VP7041e)
KWorld/JetWay/ADSTech V-Stream XPERT DTV - DVB-T USB1.1 and USB2.0
Hama DVB-T USB-Box
DiBcom reference devices (non-public)
Ultima Electronic/Artec T1 USB TVBOX
Compro Videomate DVB-U2000 - DVB-T USB
Grandtec DVB-T USB
Avermedia AverTV DVBT USB
Artec T1 USB1.1 and USB2.0 boxes
Yakumo/Typhoon DVB-T USB2.0
Hanftek UMT-010 USB2.0
Hauppauge WinTV NOVA-T USB2
The VP7041 seems to be identical to "CTS Portable" (Chinese
Television System).
These devices can be understood as budget ones, they "only" deliver
(a part of) the MPEG2 transport stream.
A firmware is needed to get the device working. See Documentation/dvb/README.dibusb
details.
Say Y if you own such a device and want to use it. You should build it as
a module.
config DVB_DIBUSB_MISDESIGNED_DEVICES
bool "Enable support for some misdesigned (see help) devices, which identify with wrong IDs"
depends on DVB_DIBUSB
help
Somehow Artec/Ultima Electronic forgot to program the eeprom of some of their
USB1.1/USB2.0 devices.
So comes that they identify with the default Vendor and Product ID of the Cypress
CY7C64613 (AN2235) or Cypress FX2.
Affected device IDs:
0x0574:0x2235 (Artec T1 USB1.1, cold)
0x04b4:0x8613 (Artec T1 USB2.0, cold)
0x0574:0x1002 (Artec T1 USB2.0, warm)
0x0574:0x2131 (aged DiBcom USB1.1 test device)
Say Y if your device has one of the mentioned IDs.
config DVB_DIBCOM_DEBUG
bool "Enable extended debug support for DiBcom USB device"
depends on DVB_DIBUSB
help
Say Y if you want to enable debuging. See modinfo dvb-dibusb for
debug levels.
