No USB devices are being noticed

No USB devices are being noticed

[Mark Healey]

I just installed Fedora 3 at work.  Everything seemed to 
work fine.  Upon first boot Kudzu noticed the printer and I 
let it configure it.  Everything seemed to work fine until I 
tried to print.  Noting, No printing, No errors dialogs.

Upon trying to fix it I noticed that the device /dev/usb/lp0 
  didn't exist.  I tried some other USB devices, a memory 
card reader and a bar code scanner.  Plugging them in caused 
no changes in the contents of /dev.  udev.d is running.

What do I check next?

Then you don't mount usbfs. Without usbfs information needed for hotplug
isn't properly exported.

How do I do that?  Especially How do I have it automatically 
done at boot.

Just works for me fine with FC3:

[root@palm etc]# grep usbfs /etc/rc.sysinit
[ -d /proc/bus/usb ] && mount -n -t usbfs /proc/bus/usb /proc/bus/usb
[ -f /proc/bus/usb/devices ] && mount -f -t usbfs usbfs /proc/bus/usb
[root@palm etc]# rpm -q -f /etc/rc.sysinit
initscripts-7.93.5-1

What is your boot / dmesg output?

So your boot code is first loading the HCDs, then unloading them.
The problem is your boot scripts doing something remarkably bogus.

HCD?

How do I determine which script and fix it?

This whole situation seems odd.  Everything worked on this 
box when windows was installed and I used the same CDs that 
I used at home where I have all kinds of USB stuff attached 
and working (except for my phone but that is a gnome-pilot 
issue).

As in "ohci_hcd".  "Host Controller Driver", as described
in the USB spec.

You could replace "rmmod" with a shell script that logged the
relevant stuff ... like maybe saving "ps -ax --forest" output
when the parameter is an HCD.  Then work backwards from there.

This is beyond me.  I've never written a shell script.  I 
wouldn't know how to rewrite rmmod anyway.

I was hoping that there was some log file I could look at.

What really sucks is that I'm doing this correspondence from 
   home and the machine in question is at work.
