131842 2003-03-29 01:28:00 Am getting errors at start up time since enabling my usb ports.
Running Mandrake 9
The error is /etc/init.d/usb line 37 read only.
Thanks 		rmcb (164)
131843 2003-03-29 03:08:00 /etc/init.d/usb is a script file which starts up a handler for the usb (probably a daemon). What is line 37 of that file? Graham L (2)
131844 2003-03-29 04:07:00 Found a fix (I think) on Mandrake forum.
I have added to /etc/modules.conf this line
probeall usb-interface uhci
Stops the error message at boot time.
Now just waiting for the courier with our new digital camera.
Here is the script file anyway. Thanks Graham L

131845 2003-03-29 04:50:00 It looks as if the script checks the /etc/modules.conf file to see if that line has been included and tries to put it in if it hasn't. For some reason, it wasn't able to, so you got the error message. Those script files need lots of testing, maybe they didn't get that one right. :_|

It's nice when something works, isn't it. :D 		Graham L (2)
