[pvrusb2] "In Kernel-2.6.18" Pvrusb2 Driver Tips

[roger]

1) During "make menuconfig" or "make xconfig":  Instead of choosing the
modules you'll need (ie. saa7115, msp3400, etc...), just choose the
pvrusb2 module within "make menuconfig" and the pvrusb2 will
automatically enable the additional drivers it will need (ie. saa7115,
msp3400, ...)  This will prevent choosing modules not needed by pvrusb2!

2) With kernel-2.6.18, pvrusb2 doesn't seem to be
creating /dev/v4l/video0 on boot whether as module or statically
compiled.  Reseting the pvrusb2 device or reloading the pvrusb2 modules
solves this.  I'm not sure why this is yet.

3) Ensure there are properly named firmware files.

For 29xxx Models:
/lib/firmware/v4l-cx2341x-enc.fw
/lib/firmware/v4l-pvrusb2-29xxx-01.fw

For the newer 24xxx Models:
/lib/firmware/v4l-cx2341x-enc.fw
/lib/firmware/v4l-cx25840.fw  
/lib/firmware/v4l-pvrusb2-24xxx-01.fw

(Firmware location definition is defined per Distribution.  I'm using
Gentoo.)
