NAME
usb_mid - USB Multi Interface Driver
SYNOPSIS
device@unit-address
DESCRIPTION
The usb_mid driver is a USBA (Solaris Universal Serial Bus Architec‐
ture)-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 creates interface nodes or interface
association nodes and attempts to bind drivers to them. If no driver is
found for interface association nodes, usb_ia(4D) is bound by default.
UGEN (Generic USB)
The usb_mid driver also supports a ugen(4D) interface allowing raw ac‐
cess to the device, for example by libusb(3LIB) applications, by pass‐
ing the drivers bound to each interface. Since a libusb application
might change the state of the device, you should not access the device
through the child interface drivers. The usb_mid driver creates a ugen
interface only if none of its children are explicitly bound to the
ugen(4D) driver. Additionally, usb_mid does not create children.

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 discon‐
nect 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.
The following messages may be logged into the system log. They are for‐
matted in the following manner:
<device path><usb_mid<instance number>): message...
No driver found for interface <n> (nodename: <string>) of <device>.
No driver is available for this interface.
No driver found for device <device>.
No driver is available for this interface.
Can't support ugen for multiple configuration devices that have at‐
tached child interface drivers.
No ugen interface is available and libusb(3LIB) cannot work with
this device.
