mt76x2u vendor request failed

[draxdeveloper]

After a random time, my MediaTek Inc. MT7612U get really slow.
When this happens, if I try to do a lsusb it's just hangs
And if I reboot, it's get stuck spamming this message:

mt76x2u 3-4:1.0: vendor request req:07 off:0430 failed:-71

I really don't know what to do, it's works but eventually will have that issue and I always forced to do a hard reset.

I have a system that runs Kubuntu 22.10. Let do some testing to see what I can figure out.

Ok, TY :)

Someone suggested this patch in ask ubuntu. But I don't know how to do it (and how to undo it if it's needed)

But I don't know how to do it (and how to undo it if it's needed)

I can help with that but first, before we make a mess, let me analyze the situation and make a recommendation.

[morrownr]

Here is my recommendation:

2023-02-05

Purpose: To test drivers on or with kernels beyond what
is currently included in the release versions of Ubuntu.

Upgrading the Linux Kernel on Ubuntu based amd64 systems

Note: Turn secure mode off before installing. These kernels
do not support secure mode.

You will need to make a directory to hold some downloaded
files, Since we are downloading a 6.1 kernel I use:

~/src/6.1

... anywhere in your home directory should work.

Go to:

https://kernel.ubuntu.com/~kernel-ppa/mainline/

Note: This guide is an example for kernel 6.1.9 Please
make adjustments for other kernels.

Download into a clean directory: (no other .deb files)

linux-headers-6.1.9-060109_6.1.9-060109.202302010835_all.deb
linux-headers-6.1.9-060109-generic_6.1.9-060109.202302010835_amd64.deb
linux-image-unsigned-6.1.9-060109-generic_6.1.9-060109.202302010835_amd64.deb
linux-modules-6.1.9-060109-generic_6.1.9-060109.202302010835_amd64.deb

---

To install:

sudo dpkg -i *.deb

Once back at the command line interface, reboot.

You can use grup during boot to decide which kernel to boot. The
default is the most modern kernel installed.

---

To remove:

Note: To remove a kernel you installed this way, you will
need to boot the computer to a different kernel.

sudo apt remove linux-headers-6.1.9*
sudo apt remove linux-modules-6.1.9*
sudo apt remove linux-image-unsigned-6.1.9*

Note: Once complete, reboot and the default kernel will now be
the most modern kernel still on your system. To select another
kernel version to boot, use the grub menu.

Happy Compiling!

Secure mode as in secure boot?

[morrownr]

Yes

[draxdeveloper]

Updated... Didn't had the USB issue yet, but it's really slow.
It's not keep in a slow speed but it's instable so it's goes from ~6mb to ~120mb

[draxdeveloper]

Update...
Did the upgrade
6.1.9-060109-generic
But, had the same issue again. (vendor request failed)
Also, since today the speed are most of time below 10mb

[draxdeveloper]

Don't know if this helps, but this is my USB list, almost all my USB are 3.0 with the exception of two.

this is my USBs

As you can see, I have 6 USB ports (and other two that are not 3.0, don't know if even is 2.0)...
But, just two of then are listed as 3.0 and it's not the ones connected to the MOBO (I tested all of them).

[morrownr]

Hmmm... this might turn into fun. Not!

Let me drag out the laptop I bought last year. It is the only system I have that is anywhere close to as modern as your setup. My big bad dev box is 10+ years old but hold on before you laugh... i7 quad core with 12 MB of ram.

Do you have any usb related settings in the bios?

USB3 is not mankind's greatest invention. I've seen plenty of USB3 problems but this is a new one on me.

[draxdeveloper]

Hum... I will have to check
