This happens when a libusb driver (e.g. WinUSB) is installed
after a device has been setup/discovered (with get_device_list).
I'm currently testing this, so that I can review the patch, but I'm not
seeing much of an issue with the original code.
I'm using a modified xusb with the following patch:

dev = libusb_get_device(handle);
-------------------------------------------------------------------------
Even as I am not going through a libusb reinit before trying to access
the device after the driver has been installed, once the driver has been
installed, libusb has no trouble communicating with the device.
Attached is the full log of what I get when installing a WinUSB driver
mid-test (look for "Please install driver NOW!"). You'll notice that we
go straight into a libusb_get_device_list() after the driver has been
installed, due to the second libusb_open... call, and everything behaves
as expected.
From these results, the only reason I'd see a need for the patch is if
we want to address the potential issue of the driver installation ending
right when we are in the middle of detecting devices, in which case we
may get a different driver landscape between passes, but, with driver
installation being so slow on Windows that's probably a one in a million
chance (i.e. even if you wanted, you wouldn't be able to ensure that
your driver installation ends right when you're issuing a
libusb_get_device_list to be able to disturb it). Either that or you're
probably issuing way more libusb_get_device_list calls than you should.
All in all, I'm not seeing a real issue with being able to install a
driver after libusb_init has been issued and access the device right
now. Unless you can produce a scenario disproving what I currently see
as a very low probability for the issue to manifest itself, I would
still motion to wait for hotplug to review our enumeration behaviour.
