I have just upgraded an old Fedora Core 2 installation to Fedora Core 3. Everything seems to be working fine, except that after upgrading, "/dev/usb" is no longer a directory containing device files, but is now a normal character device file:
# ls -l /dev/usb crw------- 1 root root 180, 0 ene 30 12:28 /dev/usb
Don't know what's going on here, but this has some nasty consequences, like UDEV being unable to create the device file for my USB printer into "/dev/usb/lp0".
I have searched in Google for similar reports but couldn't find anything related. Could anyone throw some light at this?
