usb: Early failure when the first descriptor read fails or is invalid

This may happen when using an USB1 device on a controller that only supports
USB2 (e.g. EHCI). Reading the first descriptor will fail (read 0 byte), so we
can abort the process at this point instead of failing later and wasting time.
