This is probably caused by the current dvb_usb_rtl2831u module using
dibusb_rc_keys, which disapperead due to IR changes.
Syncing the rtl2831-r2/ tree with the main archive cause compilation
problems in v4l/dibusb-mc.c and I suppose rtd2830u.c will not compile
anymore either.
Can somebody with knowledge on IR help me with updating the code ?
$ grep dibusb_rc_keys */*.[ch]
v4l/dibusb-mc.c: .rc_key_map = dibusb_rc_keys,
v4l/rtd2830u.c: d->props.rc_key_map = dibusb_rc_keys;
v4l/rtd2830u.c: .rc_key_map = dibusb_rc_keys,
v4l/rtd2830u.c: .rc_key_map = dibusb_rc_keys,
I addition, I'd like to get help on how to move the IR code into
http://linuxtv.org/hg/~anttip/rtl2831u
That (in all other respects much better) version has NO IR support at
all at. Adding IR to that driver, and getting it into the kernel would
solve all problems.

Hi,
i am using a DVB-T USB-Stick with Realtek RTL2831 chip (14aa:0160) on
Debian Lenny having the lastest Backport kernel 2.6.32.

For v4l I took the drivers from here:
http://linuxtv.org/hg/~jhoogenraad/rtl2831-r2/
The checked out source compile and installs fine. I compiled them
starting with "make distclean". But when plugging the DVB-Stick this
happens:

When plugging the usb-stick after boot I am able to use it as intend.
But when having it inserted during boot the system hangs up. Calling
lsusb from console causes the used console to hang up as well. Would be
great if anyone got a solution for this problem.
Best regards,
Thomas
