USB Metrics Devices Monitor

Credit where credit is due.

All the code here was initially grabbed from the internet by google searches. I've mentioned some of the original authors, but in the long error-search-trail-repeat hours I've certainly lost some of the original authors names.

Please file an issue when I didn't give you credit.
