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".

Third party device, with FTDI chip on it. Get this when plugging device
in. Discovered in kernel 2.6.32
Wow, that kernel is ancient. Please upgrade to a more recent kernel such
as v3.14.5, or you need to get support from whatever vendor is forcing
you to use such an old kernel.

Good luck,
Johan
