Thank you for the reply, in response to your comments, yes your comment about disabling UAS I went and uninstalled one of the packages called kmod-usb-storage-extras which says it enables support for extra USB related things. After that I had to install the package kmod-usb-storage-uas which allowed my 2.0TB UAS drive to be correctly identified on a 2.0 port but not the 3.0 port. I did try this drive on other computers and laptops and it works fine! I did not try 19.07 as I am unable to make that big of a config change at this time, and I do have a 3.0 hub on order from amazon.
i also found this bug which was IMO incorrectly marked as closed. https://bugs.openwrt.org/index.php?do=details&task_id=1862
I do have a USB 3.0 hub on order and will be here in a few days for more testing. As of now I tried the solution that [Paul Fertser] recommended at the bottom that thread and it did not work for me 
So to rehash things in an easier to understand way, I got 2 out of 3 of my external drives working correctly on my 3.0 port! I only have 1 drive left that does not work on the USB 3.0 port, a drive named:
Bus 004 Device 002: ID 174c:55aa RSH-339 ASM1153E <---- That little bugger vexes me! But I must point out again that it works great on laptops and other things. It even works great on the 3.0 port of another AC68U I have that runs Fresh tomato firmware. But it doesn't work on OpenWRT with my USB 3.0 port.
At this point I guess I should submit a bug as a web search does show my vid pid has issues with openwrt.
Net update!: As far as I can tell when i plug in the drive to the 3.0 port OpenWRt is not assigning it a storage driver! look at the output of lsusb -t:
root@AC68U-43B8:~# lsusb -t
/: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M
|__ Port 1: Dev 2, If 0, Class=, Driver=, 5000M
/: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/0p, 480M
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=ohci-platform/2p, 12M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-platform/2p, 480M
Where it says "Class=" It should say "Class=Mass Storage, Driver=usb-storage" but it does not show any driver being loaded.! This is a big breakthrough! But sadly I do not know how to manually spec a driver for it. Does anyone here?
Look at the last device, it shows no driver is being loaded!
