Thanks for the heads up. Should be easy to fix.
In related news, thanks to a very generous soul, as well as, the USB
committee's 3.0 micro-B connector [1] being all kinds of a lousy design
(side by side? seriously?), I am now the proud owner of a salvaged yet
fully working CYUSB3KIT-001 EZ-USB FX3 development board [2]:

Now, isn't this nice! :D
And I'll take this opportunity to ask anyone on this list with an FX3
dev board, who happen to break their USB micro-B connector, to get a
replacement from Cypress and then please contact either myself or
Xiaofan, as we will be most interested in taking these boards off your
hands...
But to get back on topic, now that I have an FX3 board, I've picked up a
couple additional small issues for fxload, one of which being that in
non-verbose mode, you get a LIBUSB_IO_ERROR on the last transfer. This
is expected, since our last transfer acts as a reset and effectively
makes the device disconnect from the bus, potentially with a different
VID:PID, but it would be nice to address that, so I'm planning to fix
all these issues together.
Also, for what is worth, these addons to the fxload sample will have no
impact on the 1.0.15 release. I'm hoping to be able to to push a patch
during the 1.0.15 RC, but if not, it'll just be part of 1.0.16/2.x.
