    usb: cdc_acm: Add quirk for Uniden UBC125 scanner · 4a762569
    Houston Yaroschoff authored
    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
      usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
      usb 1-4: Product: UBC125XLT
