From Kernel 3.7 pid has been removed, set to off and controlled from dvb-usbv2.
Firmware Loading Options

dvb-usb-it913x firmware=#

Number # options
0 = AUTO(default)
1 = dvb-usb-it9137-01.fw (chip version 1)
2 = dvb-usb-it9135-01.fw (chip version 1)
3 = dvb-usb-it9135-02.fw (chip version 2)

Firmware Instructions

Locate file get_dvb_firmware in scripts since kernel 4.8 (formerly was in Documentation/dvb of Kernel 3.3 and above).

For IT9135 devices

./get_dvb_firmware it9135

This will produce

dvb-usb-it9135-01.fw
dvb-usb-it9135-02.fw

Installation Instructions

Kernels 2.6.31 to 3.3 and updates
Go to the How to Obtain, Build and Install V4L-DVB Device Drivers page and download and build the lastest media_build.
Driver last updated: 09 APR 12
Driver Version: 1.28

DVR Applications

When using digital video recorder such as VDR, MythTV etc turn pid filter off.
Modify /etc/modules (or /etc/modules.preload) file and enter example;

 dvb-usb-it913x pid=1

Since driver version 1.27 PID 8192 can be used pass through entire transport stream. Since Kernel 3.7 pid filter is off.

Known Problems

PID filtering issues on some networks.
Does not work with w_scan with PID filter on. Use the -F option

w_scan -F

Issues with 9005 type devices.
Chip Version 2 on ID 048d:9135 does not tune (fixed from driver version 1.24).
Kernels 3.2 and 3.3 issues with version 2 chips on ID 0485:9135 update with media_build.
Issues with 9006 Chip version 1 devices resetting USB controller.

Warm boot from other places

Users should not reboot between operating systems without a power off cold boot. Some devices may have different tuner registers and firmware applied. The two should always match. The reverse also applies.
