[pvrusb2] driver oops [was: An Apology to the list]

[Michal Witkowski]

I had compilation issues under Ubuntu 10.04 LTS. It just can't find the kernel 
headers:

make INSTALL_MOD_DIR=pvrusb2 -C /lib/modules/2.6.32-22-generic/build 
M=/root/pvrusb2-mci-20100425/driver CONFIG_VIDEO_PVRUSB2=m 
CONFIG_VIDEO_PVRUSB2_24XXX=y CONFIG_VIDEO_PVRUSB2_SYSFS=y 
CONFIG_VIDEO_PVRUSB2_DVB=y CONFIG_VIDEO_PVRUSB2_DEBUGIFC=y 
CONFIG_VIDEO_ADV_DEBUG=y modules

........

However, I have the kernel headers installed. What else do I need? I don't know 
how to force it to have them installed. As for compiling my own kernel, I'd like 
to keep my Mythbuntu as vanilla as possible.

I installed drivers from v4l mercurial, and tried building the pvrusb2 module from
Mike's snapshot  against it using:

root at multibox:/root/pvrusb2-mci-20100425/driver# export V4LDIR=/root/v4l-dvb/
root at multibox:/root/pvrusb2-mci-20100425/driver# make

make INSTALL_MOD_DIR=pvrusb2 -C /lib/modules/2.6.32-22-generic/build

But this fails. Anyone has any idea how to fix this?

Cheers,
