Hi, Mark.
I still think your modprobe command should work.
Do you still have your 81-Agilis.rules udev rules file loaded containing:
SYSFS{idVendor}=="104d", ATTRS{idProduct}=="3000", MODE="0666"
What happens if you add another rule for model 3006?
SYSFS{idVendor}=="104d", ATTRS{idProduct}=="3006", MODE="0666"
What happens if you connect both devices, but after connecting the
second, wait 60 seconds in case the /dev/ttyUSB1 file is somehow slow to
show up?
