support for IR remote TerraTec Cinergy T USB XXS

Dear linux-media developers,

I think I found a bug in the support of the  TerraTec Cinergy T USB XXS
remote control, or maybe just a new hardware revision appeared.

When I recently bought such a USB-stick I found the remote not working,
instead 'dib0700: Unknown remote controller key' lines appearing in
syslog on each keypress. The dvb_usb_dib0700 kernel module got
autoloaded by my Ubuntu 10.10. I am using current hg revision of v4l-dvb
and load the kernel module using the 'dvb_usb_dib0700_ir_proto=0'
option. Simply adding the keycodes to the driver file
(linux/drivers/media/dvb/dvb-usb/dib0700_devices.c,
patch appended) made things work.

However, by incident I found those very keycodes are already defined in
the linux/drivers/media/IR/keymaps/rc-nec-terratec-cinergy-xs.c file, so
maybe the issue is just about loading it?

'lsusb' lists my device as
Bus 001 Device 006: ID 0ccd:00ab TerraTec Electronic GmbH
despite I do not own the 'HD' version of the device, your wiki
http://linuxtv.org/wiki/index.php/TerraTec_Cinergy_T_USB_XXS
says that ID corresponds to. The output of 'lsusb -v' is appended to
this mail.

'cat /proc/bus/input/devices' lists the input device as
I: Bus=0003 Vendor=0ccd Product=00ab Version=0100
N: Name="IR-receiver inside an USB DVB receiver"
P: Phys=usb-0000:00:12.2-2/ir0
S: Sysfs=/devices/pci0000:00/0000:00:12.2/usb1/1-2/input/input13
U: Uniq=
H: Handlers=kbd event8
B: EV=3
B: KEY=14afc336 2b4285f00000000 0 480158000 219040000801 9e96c000000000
90024010004ffc

I hope you could add support for my stick; I'd be happy to provide
further information if necessary.

Best regards
Stefan
