Bug#927173: udev: wrong device name when booting

[JB]

I managed to track this bug down to udev, but I am no expert when it comes to it, so I might be wrong. I also thought it could be the kernel when I saw the dmesg output but first I had to be sure it was not a udev issue.

At this point, I suspect it might even be a hardware issue (device which could be not respecting USB standards).

Anyway, if you think udev can be ruled out of the list of packages which could be the source of the problem, so be it. But I would gladly try to troubleshoot this issue, and since I'm now stuck on udev level, I welcome any suggestion on how to expose the problem.

Best,

JB
