By the way, the md5sums now look like this:

Notice that the cx25840 file is identical to the cx23885 file which
Ubuntu kindly provided. So should pvrusb2 load that firmware file
instead (thereby possibly eliminating the compatibility issue with other
cx25840 cards in the same system which might require the other firmware
image)?
