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 composite (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.  

UGEN (Generic USB)

The usb_mid driver also supports a ugen(7D) interface allowing raw access to the device, for example by libusb(3LIB) applications, by passing 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. Note that the usb_mid driver creates a ugen interface only if none of its children are explicitly bound to the ugen(7D) 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 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.

The following messages may be logged into the system log. They are formatted 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 attached child interface drivers.

No ugen interface is available and libusb(3LIB) cannot work with this device.
