REMOVER support without usbdevfs

[Fumitoshi UKAI <ukai@debian.or.jp>]

Hi,

I've receive the following bug reports: http://bugs.debian.org/128121

> In /etc/hotplug/usb.agent REMOVER is made from the contens of DEVICE
> which is empty if usbdevfs is not present, i.e. REMOVER will be set
> to /var/run/usb/ instead of /var/run/usb/somefile.

So is there any problem like this?

if [ "$DEVICE" = "" ]; then
 declare -rx REMOVER=/var/run/usb/`echo "$INTERFACE/$PRODUCT/$TYPE" | sed -e 's;/;%;g'`
else
 declare -rx REMOVER=/var/run/usb/`echo $DEVICE | sed -e 's;/;%;g'`
fi
