Remarks
Example Code
/* add RxUsbInterfaceClearFeature */
rc = RxFuncAdd('RxUsbInterfaceClearFeature','usbcalls','RxUsbInterfaceClearFeature')
say '+RxUsbInterfaceClearFeature(),RC=0x'd2x(rc)
/* invoke RxUsbInterfaceClearFeature */
Interface=1 /* second interface number */
Feature=0 /* feature selector to clear */
rc = RxUsbInterfaceClearFeature(Handle,Interface,Feature)
say '*RxUsbInterfaceClearFeature(),RC=0x'd2x(rc)
/* drop RxUsbInterfaceClearFeature */
rc = RxFuncDrop('RxUsbInterfaceClearFeature')
say '-RxUsbInterfaceClearFeature(),RC=0x'd2x(rc)
