Trouble hotplugging on embedded system

Trouble hotplugging on embedded system

[Wim Vinckier]

Dear list,

I'm trying to get usb hotplugging working on a embedded system but it
doesn't (seem to) work.  As far as i understand all the documents I've
read, /sbin/hotplug (depending on /proc/sys/kernel/hotplug) should be
called whenever plugging in a device.  I guess I've forgot to enable
something in my kernel configuration but I can't find what went wrong.
 I've tried 2.6.8 and 2.6.12 with busybox 1.01.

anyone any suggestion?

wim.

I think, there are some modifications needed to the hotplug to work with 
busybox. Either in shell script syntax, or something else - can't say 
exactly. Try to google for "hotplug busybox". I think, there was even a 
special version of hotplug for busybox somewhere...

Thanks

The solution was pretty easy.  I didn't loaded all the usb drivers I
needed.  After loading uhci_hcd, I got the result I wanted, my devices
were made by devfsd.
