Compiling Kernel on FC2

[Steven Pasternak]

I use FC2 and have tried to compile kernel 2.6.9-2.6.11-rc2 and have even 
tried installing the RPMs. When it goes to boot the new kernel, it doesn't 
know what usbdevfs is when it tries to mount it. Suse 9.1 didn't do this, I 
think, because it used usbfs instead. What am I supposed to do? I use 
the /boot/config-2.6.5-1.358 as the .config file (after turning off 'generic 
x86 support and setting it to athlon). I don't know if there are any other 
problems, because I reboot after kudzu says that my printer (usb) is gone. 
Thanks!
