Worthy to try at least.
I own a MR8300 but I have never tried to plug anything in the USB. I'm following this thread anyway.
An idea to investigate. Maybe the OEM firmware limits itself to USB2 performance for a matter of power consumption. USB3 demands more. On the other hand, OpenWrt try to use USB3, and the hardware can't offer the power needed. Is there a way to tell OpenWrt to limit itself to USB2 despite USB3 capable port?
Some of the USB thumb drives I have tested are only capable of USB 2 (without the additional 5 pins used for USB 3) and the problem was exactly the same. And the power they draw from the USB port is very low.
By the way.
According to the official firmware release notes for the MR8300 it appears that it even took Linksys considerable time to enable support for storage devices via the USB port on this router model. (on the box that my MR8300 V1.1 came in the USB port is still marked with "For future expansion" and no word about USB storage support)
https://downloads.linksys.com/support/assets/releasenotes/MR8300_1.1.10.210186_Customer_ReleaseNotes.txt
Given that the older EA8300 already supported USB storage devices before the MR8300 even existed and both router models are based on the same Qualcomm chips, it would seem illogical that Linksys didn't provide USB storage support on the MR8300 right from the start. Unless they were maybe facing some unexpected problem with the re-designed PCB?
I wonder if Linksys had to come up with an unusual solution to make the USB port on the MR8300 work, like implement some sophisticated load balancing or pause some other system component(s) whenever a data packet is to be sent or received from the USB port?
Interesting analysis.
So, did the OEM firmware fix this issue?. Did you inspect the MR8300 GPL to get any clue about this issue.
https://downloads.linksys.com/support/assets/gpl/MR8300_v1.1.10.210186.tar.gz
If the issue is fixed, we may need to need to know the version which contains the fix.
I tested mounting on the stock firmware - I think mine was 1.0.8 or something. It worked right away, without any issue whatsoever.
//edit
Just double checked, I was wrong: I have 1.1.8.203202
I poked around in the firmware via serial, but couldn't find anything that I considered relevant - but then again, I do not know what I am looking for.
In case somebody wants me to check something specific, let me know, I am more than happy to provide the data needed.
BTW: user is root and password is admin - in case somebody wants to poke around. The pinout and baud rate is the same as on the EA8300 and can be found on the device page of the EA8300.
Hi 
My device is MR7350, but I have the same problem. I unpacked linksys MR8300 firmware, found script service_usb.sh and saw next:
lion_usb_power_reset ()
{
echo "===> RESET LION usb power" > /dev/console
echo "68" > /sys/class/gpio/export # gpio.68 (USB_PWR_EN)
echo "out" >/sys/class/gpio/gpio68/direction
echo "1" >/sys/class/gpio/gpio68/value # pull High, then pull Low (it's active Low)
sleep 2
echo "0" >/sys/class/gpio/gpio68/value
}
From qcom-ipq4019-xx8300.dtsi:
pulldowns {
pins = "gpio55", "gpio56", "gpio57",
"gpio60", "gpio62", "gpio63",
"gpio64", "gpio65", "gpio66",
"gpio67", "gpio68", "gpio69";
function = "qpic";
bias-pull-down;
};
So, if I understand correctly, GPIO 68 should be reset to make USB to work, but it's in active-low state by default due to the dtsi definition, right? I'm not a programmer, so it's just my thoughts.

For my MR7350 GPIO is 61 and dts definition looks like this:
usb_power_pins: usb_power_pins {
mux {
pins = "gpio61";
function = "gpio";
bias-disable;
output-low;
};
};
GPIO muxed and I cannot control it.
Anyway, I'm not familiar with the new gpiod interface and don't know how to do a reset or how to properly defined GPIO in dts.
This generally works pretty well, unfortunately right now I do not have a suitable device to play with. You will need to install gpiod-tools and use gpioset to change the line state.
Here you can find some examples, one of them is relevant to your case:
gpioset --mode=time --sec=1 gpiochip0 34=0
You will need to change 34 to 61 and play with the values (0/1).
Worth to quote a note from the tool help text:
the state of a GPIO line controlled over the character device reverts to default
when the last process referencing the file descriptor representing the device file exits.
This means that it's wrong to run gpioset, have it exit and expect the line to continue
being driven high or low.
Edit: I suppose you first need to run gpioinfo and make sure that the line you want to manipulate is not [used]
I tried to configure the pin in different ways, but no luck. I also find now that the power pin is disabled due to the script above. So I don't understand in which way USB is powered.
For my MR7350:
/sys/class/gpio $ ls
export gpio34 gpio61 gpiochip0 unexport
device edge subsystem value
/sys/devices/platform/soc/1000000.pinctrl/gpio/gpio61 $ cat direction
out
/sys/devices/platform/soc/1000000.pinctrl/gpio/gpio61 $ cat active_low
0
/sys/devices/platform/soc/1000000.pinctrl/gpio/gpio61 $ cat value
0
This is from the stock Linksys firmware. The power pin is active-high and disabled. GPIO 34 is for Bluetooth.
cat /sys/kernel/debug/gpio usually gives better output. It will also show if the line in question is [not] available for manual control.
The script you mentioned tells "pull High, then pull Low", so what you need to do is
echo "1" > /sys/class/gpio/gpio61/value
/wait a sec/
echo "0" > /sys/class/gpio/gpio61/value
(assuming the GPIO is available, otherwise a change in the DTS will be needed)
I tried this using the old API. gpiochip432 + 61 = 493. Dts definition was removed to avoid 'used' status.
echo "493" > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio493/direction
echo "1" > /sys/class/gpio/gpio493/active_low
echo "1" > /sys/class/gpio/gpio493/value
sleep 5
echo "0" > /sys/class/gpio/gpio493/value
Value 0 mean no power at the USB port.
Will try later.
I don't think you need to set the pin active_low.
output-low from the earlier example has a different meaning - "set the pin to output mode with low level"
I have 5.5V, but still, errors spamming.

So, looks like it's a driver issue.
Personally, I have a MR8300ca v1.1 and I've been running 22.03 and recently snapshot and I don't have any problem with USB: I tried 3 devices (USB2 and USB3 wit ext4, ntfs and exfat) and run ksmbd and minidlna and everything is fine.
Did you do first the linksys "guided first steps" with the router? Or did you directly install openwrt firmware?
Not sure what "guided first steps" are. I followed instructions here: https://openwrt.org/toh/linksys/mr8300?s[]=linksys&s[]=mr8300.
He meant the installation process that Linksys OEM needs at first start. I guess he is trying to know if completing that process can have some influence on the USB working.
When I received the router, I plugged it and left it running for 30 minutes before flashing Openwrt. Never used the original firmware except for flashing.
Quick question, if you speak about MR8300ca, do you mean that you have a model that is targeted to the Canadian market?
For comparison, mine has the following product sticker
Yes, I bought it from Amazon Canada but really, I don't think it's any different (I have exactly the same sticker on the router but on the box there's the ca suffix).
BTW, here's my list of additional packages I use for the snapshot:
