Subject: [PATCH v3] HID: Apply quirk HID_QUIRK_ALWAYS_POLL to Edifier QR30 (2d99:a101)
Date: Thu, 27 Nov 2025 19:03:57 -0300 [thread overview]
Message-ID: <20251127220357.1218420-1-lugathe2@gmail.com> (raw)
The USB speaker has a bug that causes it to reboot when changing the
brightness using the physical knob.
Add a new vendor and product ID entry in hid-ids.h, and register
the corresponding device in hid-quirks.c with the required quirk.
Signed-off-by: Rodrigo Lugathe da Conceição Alves <lugathe2@gmail.com>
