Comment 4 for bug 13535

I researched a bit about the problem. Here are two discussions what caused the
problem:

http://lists.freedesktop.org/pipermail/dbus/2004-August/001499.html

Essentially it looks like a problem with dbus that has a too low limit for the
devices. I'll see if we can't increase this limit somewhat.
