After switching from 7.1 to 7.2 I was unable to print to my usb printer. Running printconf didn't see the printer at all (only my other parallel port printer). I tried using the custom install option and added the /dev/usb/lp0 device but it still didn't work.
If I rebooted the system or I manually restarted lpd (service lpd restart) I got a warning message about an unknown device...guess which one? To make a long story short I finally tracked the problem back to the kernel as packaged by Redhat. When I played with recompiling the kernel I found that there are two usb controllers that are loaded as modules in the usb section. You have to pick one or the other. Loading them as modules on my system ended up with no usb controller operational. The fix was to recompile the kernel selecting the first controller as inline (ie not a module). The configs are in /usr/src/linux-2.4/configs. I had to turn off binary emulation of other file system to get a successful compile. That didn't matter to me as I don't use that stuff.
