Comment 8 for bug 356049

I also get this issue. E.g., from kern.log:

If I do lsusb -v I see that usb 3-1 is:

Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

can't get hub descriptor: Operation not permitted
cannot read device status, Operation not permitted (1)

So it looks like it's some sort of internal hub (I don't have any sort of external hub attached - this is on a Macbook Pro)

I hope this might be of some help.
