No, those won't be there without the driver for them working. > If a driver reports "init_module: No such device", does that > necessarily mean that the driver doesn't recognize your hardware, With plug-and-play type devices it seems to. > or do you sometimes have to tell the driver an I/O address or IRQ > number so it can find your hardware? This is generally only a problem for ISA devices and possibly devices on the motherboard whose address is assigned by the BIOS setup. Generally the drivers seem pretty sorted at figuring it out for themselves though. Disclaimer: this is "how it looks like it's working to me" rather than being based on a formal study of what's behind that error message. -- Pigeon Be kind to pigeons Get my GPG key here: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x21C61F7F
