/usr/sbin/update-usbids.sh doesn't handle gzip usb.ids file from http://www.linux-usb.org/usb.ids

[SC]

Binary package hint: usbutils

http://www.linux-usb.org/usb.ids returns usb.ids as a gzip file - which the update-usbids.sh cannot handle using grep.

the following revised script will successfully download the usb.ids file:

#!/bin/sh

# see also update-pciids.sh (fancier)

[ "$1" = "-q" ] && quiet="true" || quiet="false"

set -e
SRC="http://www.linux-usb.org/usb.ids"
DEST=/var/lib/misc/usb.ids

# if usb.ids is read-only (because the filesystem is read-only),
# then just skip this whole process.
if ! touch ${DEST} >&2 >/dev/null ; then
        ${quiet} || echo "${DEST} is read-only, exiting."
        exit 0
fi

if which wget >/dev/null 2>&1 ; then
        DL="wget -O $DEST.new.gz $SRC"
        ${quiet} && DL="$DL -q"
elif which lynx >/dev/null 2>&1 ; then
        DL="eval lynx -source $SRC >$DEST.new.gz"
else
        echo >&2 "update-usbids: cannot find wget nor lynx"
        exit 1
fi

if ! $DL ; then
        echo >&2 "update-usbids: download failed"
        rm -f $DEST.new
        exit 1
fi

gunzip $DEST.new.gz

if ! grep >/dev/null "^C " $DEST.new ; then
        echo >&2 "update-usbids: missing class info, probably truncated file"
        exit 1
fi

if [ -f $DEST ] ; then
        mv $DEST $DEST.old
        # --reference is supported only by chmod from GNU file, so let's ignore any errors
        chmod -f --reference=$DEST.old $DEST.new 2>/dev/null || true
fi
mv $DEST.new $DEST

${quiet} || echo "Done."

[Hans Spath (h-e0jw7)]

There has been a configuration issue with the linux-usb.org webserver. If you were behind a proxy, it was possible to receive a gzip encoded response even if the client (wget) didn't indicate support for such. The issue has been resolved recently.

See https://sourceforge.net/p/forge/site-support/16108/ for details.
