Device Query

All device query functions are documented in the RTUSB-32 Reference Manual. They can be used to retrieve the USB device, all string, configurations, interfaces, endpoint and all class or device specific descriptors.

Functions in this category may only be called when the referenced device exists. A device starts to exist with the RTUConnect call of the attachment/detachment callback. It is deallocated after the respective RTUDisconnect event occurs, all pipes to the device have been closed, and all transaction notifications for all pipes in Asynch notification mode have been retrieved by the application using RTUIOWait or RTUIOWaitTimed.
