Connecting to two FT232H boards via GpioMpsseController causes Input/Output error

[FentonSheppard]

I have two FT232H FTDI boards connected to a USB hub connected to a Ubuntu PC. They are both from adafruit. Configurations for the two interfaces are attached.

error.txt
interface_a.txt
interface_b.txt

When I use GpioMpsseController and configure interface A (FT232H01A), providing its unique url "ftdi://ftdi:232h:FT232H01A/1", direction=0xFF00, frequency=1e6 and then configure B with its serial I get a usb.core.USBError: [Errno 5] Input/Output Error (see attached log).

However, if I configure interface B and then A it all works as expected.

The dmesg log in the correct instance is as follows (3.4 is interface A and 4.1 is interface B):
[ 1310.652349] usb 3-3.4.1: usbfs: interface 0 claimed by ftdi_sio while 'pytest' sets config #1

And when it fails it appears to have a missing entry for USB 3-3.4.1 (interface B):
