[Bug 53293] USB device not recognized in powered hub (patch)

Public bug reported:

"Some hubs claim not to support port-power switching, and right now the
hub driver believes them and does not enable power to their ports.
However it turns out that even though they don't actually switch power,
they do ignore all events on a port until told to turn on the power!
This problem has been reported by several users.

This revised patch (as672b) makes the hub driver always try to turn on
port power to all hubs, regardless of what the hub descriptor says.  It
also adds a comment explaining the need for this.

I have applied the attached patche to the 2.6.15 linux source  and it
works perfectly. Can this be added to the next security release of the
kernel?
