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.

You are right about open source code not being any more stable or robust when initially written. The stability advantage comes form not having to reinvent the wheel, so that when a proper solution has been found, derivative works can benefit from it more effectively.

Now of course, this also means that bugs from sloppy code can spread more easily as well. To this extent, open source relies on emergence via selective processes more than central authorities (which, I personally think is a better approach over all). However, when dealing with specialized areas that are not duplicated, but are core to the underlying framework (such as kernel development) the notion of duplication and emergence as a means of feedback selection falls apart. I recommend "The Cathedral and the Bazaar"
