I am having issues using and controlling a TIAO from a raspberry PI. I know some will wonder why I want to do this when the RPI can SPI from the GPIO. Well mainly because I don't always have the SPI interface available.
Anyway was trying to use it with Flashrom and kept getting Unknown programmer error, which means it was not finding the TIAO. However under Dev/ I see ttyUSB0 show up. sudo lsusb -v -s 001:007 shows Bus 001 Device 007: ID 0403:8a98 Future Technology Devices International, Ltd TIAO Multi-Protocol Adapter. Which makes me think things should be working.
I am wondering if I perhaps have done something to the board as I can't seem to get minicom to work either after following these instructions:

Well Minicom works but I don't seem to get any response from the TIAO board. The board seems to work fine under windows 8.1.

I also added sudo modprobe ftdi_sio vendor=0x0403 product=0x8a98 since the link above didn't seem to work for me.
At this point I am confused as I have built flashrom again, but it doesn't seem to pickup the fact that the TIAO is an option for some reason.

Ok never mind figured out flashrom issue, had to restart and make install again. However still only showing the A channel. And if I run flashrom, the unit disappears until I unplug it and plug it back in....
