| Subject: usb: cdc_acm: Add quirk for Uniden UBC125 scanner |
| |
| From: Houston Yaroschoff <hstn@4ever3.net> |
| |
| commit 4a762569a2722b8a48066c7bacf0e1dc67d17fa1 upstream. |
| |
| 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 |
| usb 1-4: Manufacturer: Uniden Corp. |
| usb 1-4: SerialNumber: 0001 |
| cdc_acm 1-4:1.0: ttyACM0: USB ACM device |
