Every time my listbox's row changes, it send out 64 of these commands.
Packaging them together might improve things - at least it would
require a whole lot less searching by the OS to find the device! I
haven't done it that way because each of the 64 pieces of data might
have to be sent to other places rather than this one particular serial
device. I suppose that I could "separate" the data first and then
dump it all at once to the various receivers. Worth a try.
Actually I think anytime you send data over USB you get a "FIND DEVICE"
like call just in case the device has been removed from the USB bus (IF
I recall my USB development work correctly)
So grouping your data should get rid of 64 different "find device
calls" but you certainly will still get some
