| Subject: usb: serial: ftdi_sio: add "bricked" FTDI device PID |
| |
| From: Perry Hung <iperry@gmail.com> |
| |
| commit 7f2719f0003da1ad13124ef00f48d7514c79e30d upstream. |
| |
| An official recent Windows driver from FTDI detects counterfeit devices |
| and reprograms the internal EEPROM containing the USB PID to 0, effectively |
| bricking the device. |
| |
| Add support for this VID/PID pair to correctly bind the driver on these |
| devices. |
