NAME

       Device::USB::PCSensor::HidTEMPer - Device overview

VERSION

       Version 0.02

SYNOPSIS

       Shared code:

	 use Device::USB::PCSensor::HidTEMPer;
	 my $pcsensor = Device::USB::PCSensor::HidTEMPer->new();

       Single-device systems:

	 my $device = $pcsensor->device();
	 print $device->external()->fahrenheit() if defined $device->external();

       Multi-device systems:

	 my @devices = $pcsensor->list_devices();

	 foreach my $device ( @devices ){
	   print $device->internal()->celsius() if defined $device->internal();
	 }

DESCRIPTION

       This module is a simplified interface to the HidTEMPer thermometers created by PCSensor. It hides any problems recognizing the correct
       objects to initialize and the dependency on Device::USB. Use of the connected thermometers can be done by either creating a array of
       objects if multiple devices are connected, or the function device() if only one device is present.

       One example of its usage can be found in the Linux Journal August 2010, "Cool Projects edition" page 32-34.

   CONSTANTS
       The following constants are declared

       o  PRODUCT_ID

	  Contains the hex value of the product id on the usb chip, in this case 0x660c

       o  VENDOR_ID

	  Contains the hex value representing the manufacturer of the chip, in this case "Tenx Technology, Inc."

       o  SUPPORTED_DEVICES

	  Contains the mapping between name and identifiers for all supported thermometers.

	   Hex value   Product	       Internal sensor	  External sensor
	   0x5b        HidTEMPerNTC    Yes		  Yes
	   0x58        HidTEMPer       Yes		  No

   METHODS
       o  new()

	  Initialize the system, and the USB-connection to be used.

       o  device()

	  Return a single thermometer instance. ONLY to be used in systems using a single thermometer device. Returns undef if no devices was
	  found.

       o  list_devices()

	  Returns an array of recognized thermometer instances if an array value is expected, otherwise it returns a scalar with the number of
	  devices found.

DEPENDENCIES

       This module internally includes and takes use of the following packages:

	use Device::USB;
	use Device::USB::PCSensor::HidTEMPer::Device;
	use Device::USB::PCSensor::HidTEMPer::NTC;
	use Device::USB::PCSensor::HidTEMPer::TEMPer;

       This module uses the strict and warning pragmas.

NAME

       usb_as - USB audio streaming driver

SYNOPSIS

       sound@unit-address

DESCRIPTION

       The usb_as driver is a USBA (Solaris USB Architecture) compliant client driver that supports the USB Audio Class 1.0 specification.

       The  usb_as  driver processes audio data messages during play and record and sets sample frequency, precision, encoding and other functions
       on request from the USB audio control driver. See usb_ac(7D).

       This driver is plumbed under the USB audio control driver and does not directly interface with the user application.

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_as<instance num>): Error Message...

       where <device path> is the physical path to the device in /devices directory.

       No bandwidth available.

	   There is no bandwidth available for the isochronous pipe. As a result, no data will be transferred during play and record.

       Operating a full/high speed audio device on a high speed port is not supported.

	   The USB software does not currently support full or high speed audio devices connected to an external USB 2.0 hub that is linked  to  a
	   port of a USB 2.0 host controller. Audio devices must be connected directly to a port of a USB 2.0 controller or to any USB 1.1 port.

       Cannot access device. Please reconnect <name>.

	   There was an error in accessing the device during reconnect. Please reconnect the device.

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

	   A  USB  audio  streaming interface was hot-removed while open. A new device was hot-inserted which is not identical to the original USB
	   audio device. Please disconnect the USB device and reconnect the device to the same port.

NOTES

       The USB audio streaming interface will be power managed if the device is idle.
