Pretty much for my entire career in Linux USB (eight years now?), we've been complaining about how USB device power management just sucks. We enable auto-suspend for a USB device driver, and find dozens of different USB devices that simply disconnect from the bus when auto-suspend is enabled.

For years, we've blamed those devices for being cheap, crappy, and broken. We talked about blacklists in the kernel, and ripped those out when they got too big. We've talked about whitelists in userspace, but not many distros have time to cultivate such lists.

It turns out it's not always the device's fault.

Fascinating bug.

Code/Product quality has nothing to do with open or closed source.

Completely agree on this.

Problems don't go away when things are open or closed. Problems like this go away when an expert tries very hard to solve a problem and eventually finds it and fixes it.

Also completely agree on this.

The reason I personally (as a developer) prefer open source is that it gives you the option to fix the code. With closed source, you don't have that option at all.

Also, even if you can't fix the code, it lets you see how the code reacts in certain cases, which coud help you find a workaround.
