DESCRIPTION

13       The  uhci  host controller driver is a USBA  (Solaris USB Architecture)
14       compliant nexus driver that  supports  the  Universal  Host  Controller
15       Interface  Specification  1.1, an industry standard developed by Intel.
16       The uhci driver supports all USB transfers, including  interrupt,  con‐
17       trol, isochronous and bulk.

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