Just as a side note, some discussion has been taking place at
https://bugzilla.kernel.org/show_bug.cgi?id=43081

The problem is, that with this setting, the USB ports are powered ALWAYS

As far as the OHCI hardware is concerned, there shouldn't be any

You, the stupid end-user, would not see this message at all under

Yes, that makes it work !
I just find one MCP51 and two MCP79 OHCI id. Can you provide more buggy

Thanks.
I have the MCP61 (rev. A2) with id 10de:03f1.
