My desktop computer has a wired connection to the internet and so the built-in wifi card is normally not used. I decided to enable and use it as a wireless access point.
Unfortunately NetworkManager will only create an ad-hoc wifi network, and Android devices will only connect to infrastructure access points. Don’t ask why… A rooted Android phone or tablet can be configured to connect to an ad-hoc network, and if a separate program can configure a Linux box to act as an access point, NetworkManager should be able to do the same. As far as I can see, there are no good technical reasons for either of these deficiencies.
The solution is

A system component crashing will activate the apport reporting system. What is really annoying about this is that the warning pop-up windows will keep appearing long after the problem is solved.

Following the default installation of wireshark it is only possible to capture packets as root, which is clearly less than ideal. It is much better to run wireshark as a non-root user:

pyUSB is an excellent Python package that can significantly simplify USB programming. For most Linux distributions there are packages only for older versions of pyUSB, but since it is actively developed you probably want to have the latest version on your system.
