That's just rich....I know a bunch of devices that use internal USB
hubs, my Verizon Wireless PCMCIA EVDO card for one. Yes, it's PCMCIA
but has an internal USB hub with the parts attached to it. Kind of
screwy but kind of interesting to...

The power limitation in the kernel could easily cause these devices to
fail to work even if they would normally work fine...

If you turn off the power limitation for USB hubs does your BT dongle
work? I remember that there was a /proc entry to override it
somehow...
