The latest production release of Lansweeper (5.3) can already detect attached printers, USB drives, keyboards and mice for instance. Printers are listed on individual computer webpages under Config\Devices\Printer and drives under Config\Disk.
5.3 doesn't return a full list of all USB connected devices though. This feature will be added in the next Lansweeper 6.0 beta release, 6.0.0.10. If you're not on our list of beta testers yet, just send a quick email to support@lansweeper.com and include "beta" in the title of your message. We'll add you to our testers and notify you as soon as the new beta becomes available.
