Thanks Johan, that's why I looked at the cross references for ftdi_sio.c 
over on
http://lxr.free-electrons.com/source/drivers/usb/serial/ftdi_sio.c, 
latest version it's showing is 3.14.  It appears that the ftdi_sio code 
is largely the same as in 2.6.32, particularly in the 
ftdi_set_max_packet_size() function.

I'm trying to verify if the "number of endpoints is 0" is a valid 
situation.

Just a typical day of "fun with kernels and devices".
