Universal USB Device Driver (USBIO)
The main dialog contains several dialog pages which allow to access the
device-related driver operations. From the dialog page “Pipes” a
separate dialog can be started for each configured pipe. The pipe
dialogs are non-modal. More than one pipe dialog can be opened at a
given point in time.
E.7.1 Dialog Pages for Device Operations
E.7.1.1 Device
This page allows to scan for available devices. The application
enumerates the USBIO device objects currently available. It opens each
device object and queries the USB device descriptor. The USB devices
currently attached to USBIO are listed in the output window. A device
can be opened and closed, and the device parameters can be requested
or set.

E.7.1.2 Descriptors
This page allows to query standard descriptors from the device. The
index of the configuration and the strong descriptors can be specified.
The descriptors are dumped to the output window. Some descriptors are
interpreted. Unknown descriptors are presented as HEX dump.
