The completed flag that may be passed to asynchronous event handlers is read at https://github.com/libusb/libusb/blob/master/libusb/io.c#L2345 guarded by the events lock, and at https://github.com/libusb/libusb/blob/master/libusb/io.c#L2358 guarded by the event waiters lock.

This means there is no unified lock to access it from other threads, making multithreaded code difficult. Perhaps it sho

Please, please, PLEASE generate HTML docs for PyUSB.

The useability of pydoc is complete crap compared to a web page - With a web page, I can easily have multiple tabs open to different sections of the documentation, there is an actual navigation interface, etc... While PyDoc works, it's minimal at best, and straight out of the 80's at worst.

PyDoc can [natively generate somewhat ugly, but q

Nice work--very helpful!
May I suggest that you include a note regarding the need to Registering Your Service. (Perhaps in the Readme.md or the wiki, which should probably be linked in the readme.md)

When I added the code to "my" app (via adding an app dependency of

Hello,
Using your awesome app for install Linux for old people, every week (many Linux installed). Which have sometimes old computer 32 bits, where Bodhi Linux can revival their machine. Bodhi Linux is based on Ubuntu LTS.
Bodhi Linux 4.x (Ubuntu LTS 16.04) is already supported by MultiBootUSB 9.2, but 16.04 is almost over, I need to install Bodhi Linux 5.x (LTS 18.04).
Bodhi Linux 5.x legacy 3

You can do cool things with blink(1) using just blink1-tool. Let's document that better.

For instance, here's a customized flashing thing:

Appears to be a python3.7 package installation problem?

glasgow repo cloned today

After following the install instructions I try to run glasgow and get the following:

480s:2000: cd ~/.local/bin/
T480s:2001: ./glasgow 
Traceback (most recent call last):
  File "./glasgow", line 11, in <module>

As the engineer who wrote this, I'm sure it all seems obvious to you :) but something that would be VERY helpful to add your website and your github README file would be two bullet lists: "What USBGuard Does", "What USBGuard Doesn't Do". Having this explained clearly would be very helpful even to those of us who are tech-savvy :) Thanks.

You should add 'not installed' section of plugins to plugin manager, so users know what plugins exist and can download them from there, or have links there...

Create a document in "/Documentation/Markdown/Reference Articles" called FlingOS-Compile-Time-Configuration and include notes on how to configure the default keyboard layout using definitions in the Kernel.Hardware project properties (and not to check-in/commit such a change).
