This page provides introductory material that describes the libUSB1 library. Currently, this provides a simplified interface to the libusb-1.0 usb user space library. However, by using this class library, rather than libusb-1.0's API directly, the maintainers of NSCLDAQ can switch to newer better(?) userspace USB libraries with minimal impact on your code.
The library defines three classes and a namespace containing unbound utilities that are primarily intended to support programming the Wiener-JTEC XXUSB controller family.
The USBException, derived from
std::exception is used to
report errors from functions and methods in this library.
The USB provides a top level wrapping
of operations that don't actually involve a specific device.
The purpose of this class is to wrap any library call stream
context required by the underlying library, and to provide
an enumeration of the devices on the USB subsystem.
Device enumeration comes in the form of USBDeviceInfo
devices. Each USBDeviceInfo object
provides access to descriptive information about a device attached to
the USB subsystem that does not require a connection to the device
itself. A method is provided, as well to open the device.
Open devices are represented by USBDevice objects.
These can be configured and set and transfers of various types
can be performed to and from the device.
The XXUSBUtil namespace provides utility functions that are intended, primarily, to allow you to manage the Wiener-JTEC XXUSB controller family (the VMUSB is a VME usb controller, the CCUSB is a CAMAC USB controller). Support is provided for enumerations that are restricted to these devices, downloading lists and executing immediate lists.
The reference pages that follow document each of these classes and the datatypes and functions defined in the XXUSBUtil namespace.
