I have a TBS IR on my 5922 DVB-S2 USB tuner, as well as others on
other cards, but I use my mceusb one.  So I put these udev rules in my
/etc/udev/rules.d/10-local.rules file:

# Hauppauge ("SMK Manufacturing, Inc. eHome Infrared Receiver") USB
MCE remote control IR receiver
SUBSYSTEM=="input", KERNEL=="event*", ATTRS{idVendor}=="0609",
ATTRS{idProduct}=="031d", SYMLINK+="lirc-mce"

# Hauppauge WinTV Nova TD-500 remote control IR receiver
SUBSYSTEM=="input", KERNEL=="event*", ATTRS{idVendor}=="2040",
ATTRS{idProduct}=="8400", SYMLINK+="lirc-nova-td-500"

# AverMedia AVerTV DVB-T Volar USB remote control IR receiver
SUBSYSTEM=="input", KERNEL=="event*", ATTRS{idVendor}=="07ca",
ATTRS{idProduct}=="b808", SYMLINK+="lirc-volar"

# TBS QBox 5922 USB remote control IR receiver
SUBSYSTEM=="input", KERNEL=="event*", ATTRS{idVendor}=="734c",
ATTRS{idProduct}=="5922", SYMLINK+="lirc-tbs-5922"

# Allow MythTV (mythtv group) access to the rtc hardware for
mythfrontend to use it for timing.
KERNEL=="rtc0", GROUP="mythtv", MODE="0660"

They allow me to use this line in my /etc/lirc/hardware.conf file to
use my mceusb IR:

REMOTE_DEVICE="/dev/lirc-mce"

I would guess that you would be able to use a rule similar to my 5922
one, just specifying the model number of your TBS card as the
idProduct value.  The lsusb command should show the correct numbers,
and also for your mceusb IR device, presuming that it also is USB, as
mine is.
