Example Code
/* add RxUsbIrqWrite */
rc = RxFuncAdd('RxUsbIrqWrite','usbcalls','RxUsbIrqWrite')
say '+RxUsbIrqWrite(),RC=0x'd2x(rc)
/* invoke RxUsbIrqWrite */
drop NumBytes /* receives number of data bytes written */
Endpoint=2; AltSetting=0; Data=copies(x2c(DB),4096); Timeout=8000
rc = RxUsbIrqWrite(Handle,Endpoint,AltSetting,NumBytes,Data,Timeout)
say '*RxUsbIrqWrite(),RC=0x'd2x(rc)
/* drop RxUsbIrqWrite */
rc = RxFuncDrop('RxUsbIrqWrite')
say '-RxUsbIrqWrite(),RC=0x'd2x(rc)
