[pvrusb2] New driver snapshot: pvrusb2-mci-20100424

Sat Apr 24 18:57:26 CDT 2010

By the way, and for the record, when I build kernels here, I usually do:

1. I always build using vanilla kernels from kernel.org (not 
distro-modified kernels).

2. I generally try to configure the kernel as flexibly as possible.  So 
I try to enable everything and configure as modules.  The resulting 
kernel therefore still isn't too large, and if there's something I later 
discover that I need, then it's usually ready to load from a nearby 
module.

Building everything as modules can of course result in a LARGE tree of 
modules, but it's just disk space and these days disk space is cheap.  
There's zero performance penalty in enabling something as a module that 
never actually gets used.

Just look at the output that it throws on the screen (the full 'make ...-C <path>/driver ...') like and tweak to your setup. If you didn't unselect stuff in kernel config, this is not required. Best way to find out is to do 'cd driver && make', modprobe -r pvrusb2, insmod the new module with full path and see if it works.
