Linksys MR8300, OpenWrt 22.03.0-rc4, USB port-powered storage devices not working

I don't think going back to the original ROM then flashing OpenWrt will make a difference but I am no expert on OpenWrt and flashing.
Have you tried a fresh install without any USB drivers, plugging in the drive then installing the drivers and utilities?

Does upgrading in place overwrite the other partition containing the original Linksys ROM?

I have now installed the release version of OpenWrt 22.03.0 the way you described on Sep 3. (the only difference being that I flashed the factory.bin from within the Linksys firmware)
The result is identical to rc4, rc5 and rc6, meaning none of my USB thumb drives work if directly plugged into the MR8300's USB port.
This week I've found an older USB 2.0 Sandisk microSD card reader at home and tried that too, bringing the total of tested devices to six. All of the six USB drives work flawlessly in this same router when I boot the Linksys firmware that I am still retaining on the other partition.

By the way, if you install the package "luci-app-advanced-reboot", then an "Advanced Reboot" entry will be added to LuCI's menu, which allows you to see what is installed on each of the two partitions.

Below is a Kernel Log from my MR8300 that shows the boot sequence with a USB thumb drive plugged into the USB port.
Maybe someone who has a working USB thumb drive and is not afraid to do a reboot can post a "good" Kernel Log for comparison?

I had an issue with my disk and decided to replace it with an SSD drive of the same capacity (1TB) in the same caddy though. Upon replacing the disk, the disk was not recognised. There were entries in the system logs about /dev/sda and /dev/sda1 but it reported a problem with the partition. The disk kept flashing as though it is trying to read and eventually stopping without the partition being mounted.

I uninstalled kmod-usb-storage and kmod-usb-storage-uas with their dependants, plugged in the drive and reinstalled and voilà la. It worked just fine. This, to me at least, confirms that if plugged in without any drivers, the disk is able to negotiate with the usb hub/port but if the driver is installed, it somehow interferes and causes the behaviour you described in your original post.

Is any of the developers reading these posts? I hope someone is. Perhaps they can shed more light on what is happening here!

Do you think you can try this method and report back with your findings?

Ok. Here is another Kernel Log. This one is from the first bootup of the MR8300 right after a "Reset to defaults" was performed. So, this is the bare firmware image, without a single setting having been changed and without any additional package having been installed. But it still doesn't like to take any USB thumb drives.

I've heard, that the UAS implementation of some host controllers and some clients is broken. AFAIK the UAS module is not necessary. Did you try to operate your SSD drive without the UAS module?

I use every USB3 storage device without the UAS module and never had a problem with any device and/or host. Just give it a try. It doesn't hurt. :wink:

Looks like I'm also having issues. Just tried copying files and while it seemed fine, it errored half way while copying a large file.

Here's my log.

Mine seems to be recognising the device though but something goes wrong at some point.

@Barney Thanks for the suggestion. Just removed it. I will switch back to the SSD disk and let you know.

According to the logs my MR8300 also recognizes all the devices I have, the problem is that a moment after the USB device was recognized something goes wrong and then the USB device is getting disconnected. This goes on and on.

Like can be seen in your log as well. The USB device is recognized:

Thu Sep 15 21:17:01 2022 kern.info kernel: [260459.563038] usb 2-1: new SuperSpeed Gen 1 USB device number 64 using xhci-hcd

... and just one second later the USB device disconnects.

Thu Sep 15 21:17:02 2022 kern.info kernel: [260460.110940] usb 2-1: USB disconnect, device number 64

The "device number" starts at 1 after a reboot and counts up by 1 every time a device is recognized. So, "device number 64" means that your device was recognized (and then disconnected) more than 60 times already.

@Barney I tested and without the kmod-usb-storage-uas it won't even load the disk to /dev/sdxx

As soon as I installed uas, it loaded /dev/sda and /dev/sda1. Unfortunately, I was not able to mount it. No specific error in dmesg

@dr123 You are absolutely right. Mine has been OK so far though. It might have tried so many times and got there in the end. I wonder if this count includes the SSD which in the end did not work as I had thought. It merely loaded it and as soon as I tried accessing the data, it worked briefly before the device becoming unavailable. The whole thing is messy. There must be a bug in the software that is specific to the MR8300, either the OS or the drivers.

Okay, loading or not loading kmod-usb-storage-uas makes no difference: you are not able to use your ssd as storage device.

Last idea: when you connect your ssd to a normal PC, does the ssd (with usb enclosure) work with or without the uas driver? If the ssd works with a PC, then (that's my personal conclusion) the mess is with the MR8300 router (hardware and/or software). Or did I miss anything?

I am experiencing the same issue. Any kind of external USB storage is being reset a short time after being plugged in. I tried various external drives as well as USB3 to sdcard adapters. See attached log.

Is this an issue only related to this device or is the whole platform range using this same SoC affected?

Hi guys. Just tried the latest release 22.03.2 and the problem is still there. How can we report this to the developers to look into this?
