Sorry, I thought you were making all decisions regarding where libusbx
is going... Who do I ask?

Checking for the presence of my USB Device (every 200ms or so) on Linux,
Mac OS X, and Windows; ejecting the Device's removable drive; checking
if/when Device is actually disconnected.

That is not at all confusing to me: with "SCSI Pass Through" libusbx
will likely allow me to communicate with my Device while maintaining its
removable drive capabilities. It may also eliminate (I hope) the
annoying side effect of detaching kernel driver under Linux.

There is nothing unclear about my needs; on the contrary, my needs are
very clear and simple:
1-maintain USB Device's removable drive read/write capability;
2-momentarily communicate synchronously with USB Device's Firmware
during a maximum of 1 to 2 seconds to do the following: [a] get Firmware
Version; [b] get configuration parameters; [c] set the Device's internal
clock; [d] set configuration parameters; [e] send the format storage
command to make the Device format its SD card;
3- while doing actions #2, USB Device's removable drive capability may
not be available during 1 to 2 seconds maximum.
