Hi Clemens,
Thanks for the information. The report from lsusb indicated that these
values:
wMaxPacketSize 0x0020 1x 32 bytes
are the same for the MidiSport and the UA25. However, there's a lot of
information from that report. Is there any other particularly relevant
data I should gather from lsusb ?
Best,

So, my question(s): Is the MidiSport just poorly designed
Yes, having to load firmware is awful, but this should not affect
latency. :)
and is there a further condition or module option
that can correct the
timing delay from that unit ?
No.
It is possible that the devices have different buffer sizes, so that
sending multiple MIDI messages at once is more difficult. Have a look
at the respective values of wMaxPacketSize that are shown in the output
of "lsusb -v". Furthermore, the devices can have different internal
buffers.
Which interface did you use for sending/receiving?
Best regards,
Clemens
