NAME
     usb_mid - USB Multi Interface Driver

SYNOPSIS
     device@unit-address

DESCRIPTION
     The  usb_mid driver is a  USBA (Solaris Universal Serial Bus
     Architecture)   compliant  nexus driver that binds to device
     level nodes if no vendor or class specific driver is  avail-
     able. The usb_mid driver attempts to bind drivers to each of
     its interfaces.

     The usb_mid driver supports the nexus device control  inter-
     face.

Devices                                               usb_mid(7D)

     Cannot access device. Please reconnect <device name>.

     This device has been disconnected  because  a  device  other
     than  the original one has been inserted. The driver informs
     you of this fact by displaying the name of the original dev-
     ice.

     Device not identical to the previous one on this port.
     Please disconnect and reconnect.

     Same condition as described above;  however  in  this  case,
     the  driver is unable to identify the original device with a
     name string.
