Uniden UBC125 radio scanner has USB interface which fails to work
with cdc_acm driver:
usb 1-1.5: new full-speed USB device number 4 using xhci_hcd
cdc_acm 1-1.5:1.0: Zero length descriptor references
cdc_acm: probe of 1-1.5:1.0 failed with error -22
Adding the NO_UNION_NORMAL quirk for the device fixes the issue:
usb 1-4: new full-speed USB device number 15 using xhci_hcd
usb 1-4: New USB device found, idVendor=1965, idProduct=0018
