-PASS WebUSB related interfaces before adding trial token via script. 
+FAIL WebUSB related properties on interfaces before adding trial token via script. assert_false: Property usb exists on Navigator expected false got true
+FAIL WebUSB related interfaces before adding trial token via script. assert_equals: Interface USBAlternateInterface exists on provided object expected false but got true
+PASS WebUSB related properties on interfaces after adding trial token via script. 
 PASS WebUSB related interfaces after adding trial token via script.
