Subject: [PATCH] HID: quirks: Add another Chicony HP 5MP Cameras to hid_ignore_list
Date: Fri,  2 Jan 2026 06:56:43 +0000	[thread overview]
Message-ID: <20260102065643.1832426-1-chris.chiu@canonical.com> (raw)

Another Chicony Electronics HP 5MP Camera with USB ID 04F2:B882
reports a HID sensor interface that is not actually implemented.

Add the device to the HID ignore list so the bogus sensor is never
exposed to userspace. Then the system won't hang when runtime PM
tries to wake the unresponsive device.
