kernel 2.6 and hotplug problem
 
Hi

I compiled my own kernel two weeks ago and everything was fine - until I forgot to activate my hotplug. So I ran (as root) /etc/init.d/hotplug start:

ken@lnc99kk:~> sudo /etc/init.d/hotplug start
Password:
Starting hotplugging services [ ieee1394 net pci usb .. ] failed

(I am using SuSE 9 Pro)

so i then looked at my log

ken@lnc99kk:~> sudo cat /var/log/messages
blah blah blah blah................................

but i do have mousedev and keybdev in my kernel! and if i plugged a USB device in my computer and started it, the log looks like this:

Can anybody help? I posted this in the newb forum but no one has answered yet. I thought I might get some help here. Thanks in advance

Well, the SuSE scripts /etc/hotplug/usb.rc try to insmod the mousedev and keybdev modules, so if you compiled them right into the kernel these scripts will fail and they'll think something is seriously wrong...

So if you mean by that that you've compiled them into the kernel, then it's probably better to compile them as modules.
If they *are* already compiled as modules, try running 'depmod' , that might as well help...

good luck,
nukkel
