DIAGNOSTICS
       All host controller errors are passed to the client drivers.  Root  hub
       errors are documented in hubd(4D).


       In  addition  to being logged, the following messages may appear on the
       system console. All messages are formatted in the following manner:

         WARNING: <device path> <ohci><instance number>>: Error message...


       Unrecoverable USB Hardware Error.

           There was an unrecoverable USB hardware error reported by the  OHCI
           Controller.  Please  reboot  the  system. If this problem persists,
           contact your system vendor.


       No SOF interrupts have been received. This OHCI USB controller is unus‐
       able.

           The USB hardware is  not  generating  Start  Of  Frame  interrupts.
           Please  reboot  the  system. If this problem persists, contact your
           system vendor.



       The following messages may be entered into the  system  log.  They  are
       formatted in the following manner:

         <device path> <ohci<instance number>): Message...


       Failed to program frame interval register.

           For  an  unspecified  reason,  the frame interval register has been
           nulled out by the Uli M1575 chip. Please reboot the system. If this
           problem persists, contact your system vendor.
