Linux/FTDI
FTDI Driver
To detect the FTDI device, install the extra module package:
apt install linux-image-extra-`uname -r`
Then either reboot, or manually load the module
modprobe ftdi_sio
Find with:
/dev/ttyUSB0
FTDI Programming
apt install ftdi-eeprom
modprobe -r ftdi_sio ftdi_eeprom --read-eeprom asmith.conf
modprobe ftdi_sio tio /dev/ttyUSB0

that means that the EEPROM is erased (all 0xff); see ftdi_read_eeprom() in ftdi.c: "Guesses size of eeprom ... will not work with blank eeprom"
> Checksum Error: aaaa 0000 > Malloc failed, aborting
these errors follow from EEPROM size being -1
with an erased EEPROM the FTDI chip falls back to the default vendor:product (which is 0403:6011)

After updating the EEPROM, you should unplug and replug the board.
