2. Revision history
Features added and bugs fixed in v9.12.18.1,
(1) First release.
3. File and folder descriptions
\32bit\IT9135_SRC.tgz ITE9135 USB device driver source code package for 32 bit CPU
\64bit\IT9135_SRC.tgz ITE9135 USB device driver source code package for 64 bit CPU
4. Feature descriptions
IT9135 Linux driver is implemented with the video for Linux (V4L) interface
that greatly simplifies software integration. It performed the tasks such as
initialization, channel bandwidth selection, channel scanning and acquisition,
, and PID filter setting. Users also have access to all the relevant
signal statistic information generated by the IC, post-Viterbi bit error
rate(BER), uncorrectable Reed-Solomon (RS) packet count, signal strength,
and signal quality indicator.
One sample program with source codes are included in the driver package.
The sample program demonstrate how to access the V4L and the device in
DVB-T mode.
For users who are not familiar with Linux & LinuxTV, please refer to 'User Guide Linux FC6-3' which
details package & player installation step-by-step.
5. Package Installation for Linux
a. Install driver with source code
Alternatively, you may compile and install the driver source code manually,
1) In the folder 'IT9135_SRC', type the following command to compile & install it9135 DVB-T driver dvb-usb-it9135.ko.
# make clean
# make
# make install
2) Plug in the device and check the message to make sure the driver is work normally.
# cat /var/log/messages
log messages:
dvb-usb: found a 'ITEtech USB2.0 DVB-T Recevier' in warm state.

6. Driver uninstall
To remove ITE's driver, input
make remove
To delete .ko files, input
make clean
7. Remote Controller support
To enable IR Remote Controller, the configuration settings in EEPROM should be set properly
The IR type supported is NEC or RC-5, the configuration is set in EEPROM.
By default, The IR type for the Remote Controller shipped with 9135 USB dongle, is
consistent with EEPROM setting.
If the RC is acquired elsewhere, you should run ITE's EEPROMEdiotr in Windows to program the
IR type field properly.
RC key mapping table,
The RC key mapping table is stored in af35irtbl.bin.
A "Windows" tool IR_Editor.exe from Afa is available for users to customize the key mapping table.
8. Known problems & limitations
a.CPU architecture:
Currently only x86 architecture is supported.
b.USB support:
Currently only USB2.0 is supported.
c.Device VID/PID:
0x048D/0x9005; 0x048D/0x9006.
d.IR is supported and IRTable is named "af35irtbl.bin".
