TUSB2077A is not working with Linux

Other Parts Discussed in Thread: TUSB2077A

I made a board to evaluate the TUSB2077A hub controller and after building it I tested it with a Windows 7 PC and it appeared to work fine.  However when connected to a Raspberry Pi USB port it did not work.  The HUBCFG pin was asserted, but the downstream ports were not seen by the Raspberry Pi.  Has anyone used this controller with a Linux host?
