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 of a com-
       posite (multi interface) device if no vendor or class specific driver is available. The usb_mid driver attempts to bind drivers to each	of
       the composite device's interfaces.

DIAGNOSTICS

       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> (usb_mid<instance number>): Error Message...

       Cannot access <device>. Please reconnect.

	   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 device.

       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.

       Please disconnect and reconnect this device.

	   A hotplug of the device is needed before it can be restored.
