| Subject: USB: serial: ch341: add new Product ID for CH340 |
| |
| From: Igor Moura <imphilippini@gmail.com> |
| |
| commit 5d0136f8e79f8287e6a36780601f0ce797cf11c2 upstream. |
| |
| Add PID for CH340 that's found on some ESP8266 dev boards made by |
| LilyGO. The specific device that contains such serial converter can be |
| seen here: https://github.com/LilyGO/LILYGO-T-OI. |
| |
| Apparently, it's a regular CH340, but I've confirmed with others that |
| also bought this board that the PID found on this device (0x7522) |
| differs from other devices with the "same" converter (0x7523). |
| Simply adding its PID to the driver and rebuilding it made it work |
| as expected. |
