Subject: [PATCH v7 2/2] media: uvcvideo: add Razer Kiyo Pro to device info table
Date: Thu, 9 Apr 2026 17:28:31 -0700 [thread overview]
Message-ID: <20260410002831.1046407-3-jp@jphein.com> (raw)
In-Reply-To: <20260410002831.1046407-1-jp@jphein.com>
Add a device entry for the Razer Kiyo Pro (1532:0e05) with quirks to
work around firmware bugs that crash the xHCI host controller:
UVC_QUIRK_CTRL_THROTTLE - rate-limit control transfers to prevent
firmware lockup under sustained load
UVC_QUIRK_DISABLE_AUTOSUSPEND - prevent runtime suspend
UVC_QUIRK_NO_RESET_RESUME - skip post-reset reinitialization
The firmware (v1.5.0.1) has two failure modes: it stalls endpoints
under rapid control transfers (~25 without delay), and it fails to
reinitialize properly after USB power state transitions. Both can
cascade into xHCI controller death, disconnecting all USB devices on
the bus.
Bug reproduced on two separate Kiyo Pro units running simultaneously,
confirming the issue is not unit-specific.
