DIAGNOSTICS

       All host controller errors are passed to the client drivers. Root errors are documented in hubd(7D).

       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> <uhci><instance number>>: Error message...

       No SOF interrupts have been received. This USB UHCI host controller is unusable.

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