Hi everyone!

I'm new to this list and I joined because I stumbled upon a problem I could not find mentioned anywhere.

I have a usb device (a bluetooth dongle) that reports a product id of 0x0000. When I try to attach this to a domain I get a "missing product" error.

I checked the sources (0.6.3) and found in domain_conf.c lines 1645 following a check for a product id different from 0. If I remove this check and recompile everything works fine. I can attach the device to the virtual machine and it is recognized.

I don't know the background of this check and if disabling it has any negative consequences so I would be happy about any comments.

Sounds like the code just wasn't expecting '0' to be a valid product code. The check that is tripping you up on is assuming that if product == 0, the user didn't specify any product in the xml. The thing to do is to initialize 'product = -1' at the beginning of that function (and add a quick comment that '0' is a valid value), and then update the checks at the end of the function accordingly. - Cole
