Yes, having to load firmware is awful, but this should not affect

latency.  :)

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,
