You might look into UDEV rules... and setting up aliases for each device
based on its identifiers. I've got a similar thing going on with a
RigBlaster and another USB audio device... The Serial control lines were
getting mixed up until I set the RB to always come up as /dev/ttyUSB-RB and
the serial GPIO on the USB soundcard to /dev/ttyUSB-SCGP... These survive
reboots because they're set in the UDEV rules. (this is all complicated by
the addition of an Edgeport-8, so there are at any one time, at least 10
usb-serial devices plugged into this machine at one time.)
Whenever I reboot, the RB still comes up as /dev/ttyUSB-RB, etc.. so I
don't need to hope that /dev/ttyUSB0 always is the RigBlaster and
/dev/ttyUSB9 is the serial GPIO...
It might help, it might not, but it's worth looking into.

At least it works on Linux.
