    MacBook Pro Retina + Parallels + USB3

      Hey folks--

      We've noticed some issues with the following setup: MacBook Pro Retina (host) + Parallels 7 + Win7 or Linux (guest).  We were wondering if anyone else had tried this configuration with the FX3.

      The firmware we're testing works great on Win7 (native) and Linux (FC17, native) as well as the MacBook Pro Retina (native).  Parallels only recently provided support for USB 3.0 in guests (maybe a month or two ago).  In the above configuration, control transfers work just fine.

      On Windows gues, PC to Device bulk transfers work just fine.  Endpoint 2.  However, Device-to-PC transfers "hang".  Our Beagle trace shows the frames through the last control transfer, then start "Periodic Timeout".

      On Linux guest, both directions appear to hang with the same "Periodic Timeout".

      We've started a support ticket with the folks at Parallels to investigate, but it will take a while before we reach a support tier with sufficient technical involvement to know if this is something on our end or their end or somewhere in between.  Just curious if anyone else here has replicated the issue.
