Subject: [PATCH 2/3] usb: quirks: Add ShanWan gamepad to quirk list
Date: Sun, 26 Jul 2026 18:50:39 +0530 [thread overview]
Message-ID: <20260726132039.28330-3-ishaan.dandekar@gmail.com> (raw)
In-Reply-To: <20260726132039.28330-1-ishaan.dandekar@gmail.com>
The ShanWan Wireless Gamepad (dongle ID 2563:0575) crashes with a -71 EPROTO error during standard enumeration because it expects a 255-byte initial configuration request. Add this device to the quirk list to use the USB_QUIRK_WINDOWS_CONFIG_REQ_SIZE flag.
