It’s possible to blacklist a single USB device from connecting to Linux, while allowing similar USB devices to connect.

However I wanted a second USB Bluetooth host, integrated as part of my new WiFi card, to still work.
I’ve been a bit lax with the blog updating. In Part 1 of this post I promised Part 2 “soon” and here it is, eight weeks later. Oops.
This two-post series, aimed at embedded device beginners, explains some differences between Arduino and Raspberry Pi. In this second part we’re going to focus on one particular issue – “real-time” constraints. We’ll also quickly look over some of the alternative devices available.
