I'm using Cypress bulkloop.hex firmware on an fx2lp (CY7C68013A) with simple
host-side user-land code to transmit data to EP2 (out endpoint) and read the
'echo' on EP6 (in endpoint). The very first time the code is run it writes,
say, 60 bytes to EP2 and reads the echo (60 bytes) from EP6. When

Pardon the very long lines. This has been fixed now.
My usbmon shows the following:
--- (1) Test for 12 bytes TX/RX _without_ writing the extra 1 byte bulk
--- packet ---
(12 byte tx/rx: run program for first time)

eb13c640 4268765473 C
This is even more bizarre, the output below is from usbmon when I do two
12-byte writes/reads within the same program (in the previous example I
posted I did 2 12-byte writes/reads by calling my program twice).

Ah yes, everything works now. See below:
