Add delay to make sure that audio urbs are not sent too early. Otherwise the device hangs. Windows driver makes ~2s delay, so use about the same time delay value. snd_usb_apply_boot_quirk() is called 3 times for my MOTU M4, which is an overkill. Thus a quirk that is called only once is implemented. Also send two vendor-specific control messages before and after the delay. This behaviour is blindly copied from the Windows driver.
