Example Code
/* add RxUsbEndpointClearHalt */
rc = RxFuncAdd('RxUsbEndpointClearHalt','usbcalls','RxUsbEndpointClearHalt')
say '+RxUsbEndpointClearHalt(),RC=0x'd2x(rc)
/* invoke RxUsbEndpointClearHalt */
Endpoint=0 /* default control endpoint */
Endpoint=128+1 /* isochronous endpoint */
rc = RxUsbEndpointClearHalt(Handle,Endpoint)
say '*RxUsbEndpointClearHalt(),RC=0x'd2x(rc)
/* drop RxUsbEndpointClearHalt */
rc = RxFuncDrop('RxUsbEndpointClearHalt')
say '-RxUsbEndpointClearHalt(),RC=0x'd2x(rc)
