From 2b8be6a0d3623e65647ca199f1db6c04b051b815 Mon Sep 17 00:00:00 2001 From: Stephan Brunner Date: Wed, 18 May 2022 18:15:14 +0800 Subject: [PATCH] USB: serial: ch341: add support for GW Instek USB2.0-Serial devices stable inclusion from stable-v5.10.101 commit a21e6b2e0864877681936d30511ea1e7e6e0fc37 bugzilla: https://gitee.com/openeuler/kernel/issues/I5669Z Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=a21e6b2e0864877681936d30511ea1e7e6e0fc37 -------------------------------- commit fa77ce201f7f2d823b07753575122d1ae5597fbe upstream. Programmable lab power supplies made by GW Instek, such as the GPP-2323, have a USB port exposing a serial port to control the device. Stringing the supplied Windows driver, references to the ch341 chip are found. Binding the existing ch341 driver to the VID/PID of the GPP-2323 ("GW Instek USB2.0-Serial" as per the USB product name) works out of the box, communication and control is now possible. This patch should work with any GPP series power supply due to similarities in the product line.
