Subject: USB: storage: Ignore driver CD mode for Realtek multi-mode Wi-Fi
|
|
dongles
|
|
|
|
Many Realtek USB Wi-Fi dongles released in recent years have two modes:
|
|
one is driver CD mode which has Windows driver onboard, another one is
|
|
Wi-Fi mode. Add the US_FL_IGNORE_DEVICE quirk for these multi-mode devices.
|
|
Otherwise, usb_modeswitch may fail to switch them to Wi-Fi mode.
|
|
|
|
Currently there are only two USB IDs known to be used by these multi-mode
|
|
Wi-Fi dongles: 0bda:1a2b and 0bda:a192.
