Subject: [PATCH v2 2/2] usb: quirks: Add ShanWan gamepad to quirk list
Date: Sun, 26 Jul 2026 22:44:23 +0530	[thread overview]
Message-ID: <20260726171423.42850-3-ishaan.dandekar@gmail.com> (raw)
In-Reply-To: <20260726171423.42850-1-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.
