It might be wise to add Vendor ID to the list, as there could be different firmware for different vendors (mine is: 2237)
Not sure if this is of any use either, but rev is 326, and version, as seen via Desktop app is 2.4.0, unsure if there is any correlation between these in relation to firmware being used.
Also, though I've included it, and I'm fairly sure it's not of much real use for people to use for nefarious purposes, I'm still a little leery about posting serial numbers, but that's just me
