The USB boards are identified by an identification called USB ID.

1. All devices operating in MTP mode are supported. Note: The MTPdrive is not a replacement for the device's factory (or Windows default) device driver. You must be able to connect your device to the.
2. Install TechnoTrend AG TechnoTrend DVB-T USB 2.0 BP Device driver for Windows 7 x64, or download DriverPack Solution software for automatic driver installation and update. Download Download DriverPack Online.

The lsusb command allows identifying the USB IDs:

Newer camera devices use a standard way to expose themselves as such,via USB Video Class. Those cameras are automatically supported by theuvc-driver.

AMD Rolls Out Its First 2021 Graphics Driver - Get Radeon 21.1.1 Intel Adds Support for Iris Xe Max Graphics (DG1) - Get Version 27.20.100.9168 The New RTX 461.09 Graphics Driver Adds Support for NVIDIA’s A40 GPU.

Older cameras and TV USB devices uses USB Vendor Classes: each vendordefines its own way to access the device. This section containscard lists for such vendor-class devices.

While this is not as common as on PCI, sometimes the same USB ID is usedby different products. So, several media drivers allow passing a card=parameter, in order to setup a card number that would match the correctsettings for an specific product type.

The current supported USB cards (not including staging drivers) arelisted below[1].

Note

1. This documentation is outdated. Please check at the DVB wikiat https://linuxtv.org/wiki for more updated info.
2. deprecated: Newer DVB USB drivers should use the dvb-usb-v2 framework.

In March 2005 I got the new Twinhan USB2.0 DVB-T device. They provided specsand a firmware.

Quite keen I wanted to put the driver (with some quirks of course) into dibusb.After reading some specs and doing some USB snooping, it realized, that thedibusb-driver would be a complete mess afterwards. So I decided to do it in adifferent way: With the help of a dvb-usb-framework.

The framework provides generic functions (mostly kernel API calls), such as:

• Transport Stream URB handling in conjunction with dvb-demux-feed-control(bulk and isoc are supported)
• registering the device for the DVB-API
• registering an I2C-adapter if applicable
• remote-control/input-device handling
• firmware requesting and loading (currently just for the Cypress USBcontrollers)
• other functions/methods which can be shared by several drivers (such asfunctions for bulk-control-commands)
• TODO: a I2C-chunker. It creates device-specific chunks of register-accessesdepending on length of a register and the number of values that can bemulti-written and multi-read.

The source code of the particular DVB USB devices does just the communicationwith the device via the bus. The connection between the DVB-API-functionalityis done via callbacks, assigned in a static device-description (structdvb_usb_device) each device-driver has to have.

For an example have a look in drivers/media/usb/dvb-usb/vp7045*.

Objective is to migrate all the usb-devices (dibusb, cinergyT2, maybe thettusb; flexcop-usb already benefits from the generic flexcop-device) to usethe dvb-usb-lib.

TODO: dynamic enabling and disabling of the pid-filter in regard to number offeeds requested.

6.2. How to use?¶

6.2.1. Firmware¶

Most of the USB drivers need to download a firmware to the device before startworking.

Have a look at the Wikipage for the DVB-USB-drivers to find out, which firmwareyou need for your device:

6.2.2. Compiling¶

Since the driver is in the linux kernel, activating the driver inyour favorite config-environment should sufficient. I recommendto compile the driver as module. Hotplug does the rest.

If you use dvb-kernel enter the build-2.6 directory run ‘make’ and ‘insmod.shload’ afterwards.

6.2.3. Loading the drivers¶

Hotplug is able to load the driver, when it is needed (because you pluggedin the device).

If you want to enable debug output, you have to load the driver manually andfrom within the dvb-kernel cvs repository.

first have a look, which debug level are available:

should do the trick.

When the driver is loaded successfully, the firmware file was inthe right place and the device is connected, the “Power”-LED should beturned on.

At this point you should be able to start a dvb-capable application. I’m use(t|s)zap, mplayer and dvbscan to test the basics. VDR-xine provides thelong-term test scenario.

6.3. Known problems and bugs¶

• Don’t remove the USB device while running an DVB application, your systemwill go crazy or die most likely.

6.3.2. USB1.1 Bandwidth limitation¶

A lot of the currently supported devices are USB1.1 and thus they have amaximum bandwidth of about 5-6 MBit/s when connected to a USB2.0 hub.This is not enough for receiving the complete transport stream of aDVB-T channel (which is about 16 MBit/s). Normally this is not aproblem, if you only want to watch TV (this does not apply for HDTV),but watching a channel while recording another channel on the samefrequency simply does not work very well. This applies to all USB1.1DVB-T devices, not just the dvb-usb-devices)

The bug, where the TS is distorted by a heavy usage of the device is gonedefinitely. All dvb-usb-devices I was using (Twinhan, Kworld, DiBcom) areworking like charm now with VDR. Sometimes I even was able to record a channeland watch another one.
