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. Signed-off-by: Ishaan Dandekar <redacted> --- drivers/usb/core/quirks.c | 3 +++ 1 file changed, 3 insertions(+)
