I've gone back to 1.12.x and it works as expected

The other observation is, on the modem there is an LED
After the modem startup sequence the LED will go solid blue
with 1.13.x the LED just keeps flashing Blue?

I'm wondering if the port isn't powered up properly in the ath79 case.
What if you try a USB stick? Does it detect that and let you do the USB storage setup?

Looks like your guess is correct.
USB drive is not detected with 1.13.x
1.12.x same drive was detected
Nothing in the logs either as a double check

I looked at the OpenWrt configs for this family of devices (AR150 & AR300M/AR300M16) and in 19.07 it seems they're in the middle of the ar71xx->ath79 transition: the AR300M (NOR only)/AR300M16 have both ar71xx and ath79 board definitions but the ath79 definitions are commented out while the AR150 appears to have both ar71xx & ath79 board definitions active. For the AR150 Gargoyle is using the ath79 board definition - perhaps there are still issues not resolved with the USB support in the ath79 board definition. Testing both OpenWrt 19.07 ar71xx and ath79 AR150 images might help confirm this.
Edit: can you check the state of GPIO 6? if I understand the definition correctly this needs to be high (1) for the USB port to be enabled - see
OpenWrt GPIO docs. The GPIO needs to be declared as output.
Check the GPIO base value first as described in the Software section of the docs - if base is non-0, add it to the 6 in what follows. To see if the GPIO is visible first:
looking for gpio6.
If visible, check the state:
If it isn't visible, then with the USB device unplugged:
Code: Select all
echo "6" > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio6/direction
echo "1" > /sys/class/gpio/gpio6/value
Then plug in the device and see whether the logs show any detection.
Pity about lsusb being missing - my bad for not checking it was available.

Hmmm... "usb-phy" doesn't exactly match the spelling in the device tree ("usb_phy") for the GPIO linkage but it's close enough, try:
If that returns 0, try:
Code: Select all
echo "1" > /sys/class/gpio/usb-phy/value
/sys is sysfs so not a normal filesystem; I'm not surprised that nano fails.

That suggests the USB port should be powered up.
Just for completeness, could you also try:
Code: Select all
cat /sys/class/gpio/usb-phy/direction
I'd expect the output to be "out", in which case I'm out of ideas.
