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