The extension does not work with 64 bit5 or any of the address expressions supported by SDA. Format USB HELP [command-name] 2 Parameter command-nameA The name of a USB SDA command. When you enter the HELP commandC with a command name, a list of all the command keywords used with( the command is displayed.ww­÷ÿIm·³© 1 OBSOLETE8 These are command are left from a previous stand-alone program and not part of SDA.2 CLSC Erases the display and sets the cursor to the top of the display.

The default controller is alwaysI OHA0 even if the system does not have an Open Host Controller Interface controller. Format USB SET CONROLLER OHB0: 3 Parameter device-name:D The name of the device whose characteristics are to be added. The device name has the form ddcu where:> dd is the device code - for example, OH (The dri ver nameA corresponds to the device code; in this case, the driverA name would be SYS$OHCIDRIVER. Supported devices are OH, EH, and UH.3 c is the controller designation A through Z;C u is the unit number for USB controllers, which is always 0.; OpenVMS device names consist of the two-character device@ code, followed by the controller designation, the unit number5 (which can be 1 to 4 characters), and a colon (:).2 UHCI I Used to  set UHCI driver behavior. Presently the only supported item is diagnostic tracing.3 TRACEJ Enable event tracing using the tracing capability in SDA. You must loadB and start tracing in order for this command to become effective. Format!
