Subject: /etc/hotplug/usb/speedtouch runs multiple times at boot

Date: Tue, 11 May 2004 00:37:42 +1200

Package: speedtouch
Version: 1.2-rel-1
Severity: normal

I added some code to /etc/hotplug/usb/speedtouch to find out why my
Linux 2.6.5 system takes so long to load the speedtouch firmware during
boot, and found that the script is run 19 times at boot, once for the
USB device, once each for the three USB interfaces, and another five
times for each USB interface but under the PCI namespace:

It seems to me that further processing should only take place in the
first instance, i.e. when $DEVPATH matches bus/usb/devices/usb/* but not
bus/usb/devices/usb/*/*.

    case "$DEVPATH" in
        bus/usb/devices/usb/*/*) exit 1 ;;
        bus/usb/devices/usb/*) ;;
        *) exit 1 ;;
    esac

I don't know how well this would work on Linux 2.4, though.

This is an hotplug bug, but I did not have time yet to investigate it.

According to a comment in /etc/hotplug/usb.agent:

So there should still be some kind of test to only run once rather than 
four times, as long as $DEVPATH is set (i.e. running on Linux 2.6).

I've now tried this on Linux 2.6.6, and the speedtouch script was run 
four times, once for the device and once for each interface.  However, 
ppp didn't work and khubd Oopsed, which seems to be a known problem:

Regardless of whether this is a speedtouch bug, a hotplug bug or a 
kernel bug, the attached patch makes my PC boot much more smoothly.
