It's 0403:bcd9. The chip is a FT2232D, with one port being used for asynchronous serial and the other bit-banging JTAG debug.

Is there a way to configure the driver to look for that chip? Is there a way to tell it to use the right half and ignore the wrong one?


Have you tried using modprobe usbserial, with the appropriate product and
vendor arguments, to force usbserial to see the device ?

Major warning: Do this at your own risk and make sure that you have not
got anything important running or unsaved when you do this. :-) There may
be very good reasons why usbserial is not seeing your device.

Check the dmesg and lsmod output first to make sure that another module
hasn't been loaded (which you will to first need to unload) instead of
usbserial - I have a 3G modem that is initially loaded as a cdrom device
until I unload the module (with rmmod) and then force usbserial to see it
by specifying the vendor and product arguments to modprobe.

Doesn't work -- oh well. It's looking like the long range solution is to patch ftdi_sio.c with appropriate code and recompile. I've found a page which lists a patch for the Olimex JTAG programmer, of which I think the Luminary part is a clone.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.

PS: BTW, nice book (at least of what I've read so far).

I'm glad you like it, and hope that you're finding it useful. The part that I'm building is in support of a seminar series from the book, if the implementation details don't drive me crazy.
