Yes, and besides the errors, everything else seems to work properly. I did
notice that the one machine uses an AMD processor and all the others are Intel,
not sure what that would have to do with anything, but it is a major system
configuration difference.
Thanks for the debug level information. I will probably just shut off all
messages but it would be nice to have a way to turn them on if I need to debug
something on a remote system.
How about the libusbxhid debug messages? Since they are controlled with
{$ifdef DEBUG_MSG} you can’t really turn them on and off without re-compiling.
Could another variable be used to make libusbxhid messages optional but only if
{$ifdef DEBUG_MSG} is used? It would be helpful to be able to hide them most
of the time but show them if trying to debug without re-compiling.

I would chalk this up to differences between OS versions, configurations,
devices, etc and move on. I see all memory is released. At least it does not
crash and burn badly.
The function call you want to play with is:
libusb_set_debug
http://libusb.sourceforge.net/api-1.0/group__lib.html#ga5f8376b7a863a5a8d5b8824feb8a427a
Of course, you can set the level dynamically, from your program.

At least I can shut off the messages with that.. but any idea what these
messages actually mean? It’s an init_device error but no one was tying to do
anything but get the list of devices from the system.
Is there a description of the verbosity level anywhere?
Is this a variable I can change during program execution without re-compiling
it? It would be helpful if I was having an issue to turn on debug info, then
turn it back off without exiting my program or needing to compile.
