Dear all, I had the chance to write my first Quirk-PR and therefore took some time looking at the FreeBSD usb system. I am thinking that the solution there is is not the ideal one. Through mailing list discussions I read, I also have the impression, that the usb part of the cam subsystem is kind of a problem child. I read through parts of the usb code and am kind of understanding it. So I am trying to make an attempt to help improving it. That means, that I would like to discuss some ideas and in case this is wanted, volunteer to do some coding.
What I was thinking so far is: Since Windows and Linux can handle most of the the devices FreeBSD needs a quirk for out of the box, and at least in the case of linux, I believe they do not hold all quirks in a db, there must be a way of doing it. My idea so far is to do something like this: - When a usb device is connected, try to use it without quirks. - If it stalls, cache device id data - Then emulate a disconnect/connect - Then try all permutations of possible quirks (most common to less common?) for the device - As soon as one permutation causes device not to stall -> done Anyhow my knowledge concerning the topic is not too in-deep, but I would be happy to gather some feedback concerning my idea and maybe about other approaches in this area.
