A little script using busybox to extract all pci and usb modaliases strings and generate JSON request to some server.

modaliases.sh

#!/bin/busybox sh

JSON="$(echo '{"modalias":['; find /sys -name modalias -exec cat {} \; 2>/dev/null | grep -e '^\(pci\|usb\)' | sort | sed 's/^/"/' | sed 's/$/",/\'; busybox echo -n ']}')" # Find all pci/usb modaliases.
JSON="$(echo $JSON | sed 's/, ]}/]}/' | sed 's/\s\+//g')" # Remove trailing comma and white-space characters.
wget -q --header 'content-type: application/json' --post-data "$JSON" http://localhost:8000 -O -
