[Solved] USB type-C hub driver error

[Funtast]

Hi!

I have bought a USB type-C hub which includes 4 USB 3 ports, HDMI and Ethernet. Here I found a review online - https://www.itpro.com/software/video-co ... -performer

The hub works fine in Windows with the exception that I get a warning that my type-C port (I am using Acer Aspire A515-52G https://www.acer.com/ac/en/US/content/s ... oduct/7778) does not support the HDMI adapter.

In Linux however I get the following dmesg:

[ 8195.586706] usb usb2-port2: Cannot enable. Maybe the USB cable is bad?

and after a few minutes my whole system freezes

my kernel is : Linux Aspire 5.4.0-73-generic #82-Ubuntu SMP Wed Apr 14 17:39:42 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

I have also tried 5.8 and also 5.12-mainline but the problem persists.

I think that the issue is somewhere in the kernel and is connected to the lack of hardware support for the HDMI. However I don't know how to submit bug report and also where to submit it.

In the meantime can I just disable the part of the hub which causes the message "usb usb2-port2: Cannot enable. Maybe the USB cable is bad?" to pop again and again? And is there anything else I can do?

Thanks!

Update: now I tested it again with 5.4.0-73-generic and cinnamon entered fallback mode:

also if the dongle stays plugged in I believe after the kernel freeze I see message related to some kworker thread being blocked for too long. So there's smt like deadlock?

Unfortunately I don't have a clue of what can be done as a workaround for this problem :/

[hglee]

Maybe the USB cable is bad?" to pop again and again? And is there anything else I can do?

For starters: Disable Secure Boot in your BIOS/EUFI. If you dual-boot Windows, disable Fast StartUp [1m53s @YouTube] in Windows power options. Then:


Open a new Terminal window (Ctrl-Alt-T) then copy-and-paste the following command-line...

Code: Select all

inxi -Fxxxrz && lsusb && lspci

Post the output of that command-line, using the usual bbcode code tags to format the text for this forum.

I am not sure about secure boot - I think it's enabled. Also I do use dual boot for Windows and before at some point I tried to play around with clover and macOS. I know about the fast startup which is hybrid sleep as I understand it and I haven't disabled it but when I quit Windows I always restart, enter linux and then quit which resolves the problem. I would have noticed the problem because I have NTFS partition which is mounted readonly when I shutdown windows with fast startup.

here's the output from the command:

I inserted the hub before I ran the commnad and also I have another hub with lots of devices attached as you can see

I will also make sure secure boot is disabled. I don't have any knowledge about secure boot - could someone explain(or share resource) what it's supposed to do?

Edit: I opened the secure boot link which didn't notice before - so it seems that secure boot just disables loading untrusted drivers?

Thanks

Disable Windows Fast Startup. Fast Startup keeps Windows kernel drivers loaded into system memory and triggers during the system startup sequence. A portion of the Windows kernel is loading at the same time the Linux kernel is loading. That's a problem.....

It's not the fast startup unfortunatelly - I disabled it and the problem persists. I am pretty sure that when it was enabled, by restarting the machine instead of using shut down button, I avoided the fast startup.

Does your laptop support "HDMI over USB-C"? Not all of them do.

Yes indeed it does not support USB-C DisplayPort Alt Mode, but my dongle has usb hub and ethernet which I want to use.

I finally found a solution to my problem

Code: Select all

cd /sys/devices/pci0000:00/0000:00:14.0/usb2
cat busnum 
2
cat idProduct 
0003
cat idVendor 
1d6b

Code: Select all

usb-devices
#here I was expecting Port=02
T:  Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=  1 Spd=10000 MxCh= 0
D:  Ver= 3.10 Cls=09(hub  ) Sub=00 Prot=03 MxPS= 9 #Cfgs=  1
P:  Vendor=1d6b ProdID=0003 Rev=05.11
S:  Manufacturer=Linux 5.11.0-25-generic xhci-hcd
S:  Product=xHCI Host Controller
S:  SerialNumber=0000:00:14.0
C:  #Ifs= 0 Cfg#= 0 Atr= MxPwr=

so I added a udev rule to disable this device and now the hub and ethernet adapter are working and I no longer get:
"usb usb2-port2: Cannot enable. Maybe the USB cable is bad?"

Code: Select all

echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="1d6b", ATTRS{idProduct}=="0003", ATTR{authorized}="0"' > sudo tee /etc/udev/rules.d/disable_usb_hdmi.rules

Hopefully someone may find this helpful - I know I had to search through everything to find what I need to disable. Also I still believe this is linux kernel bug and the usb driver should just skip initialization of this speciffic part of my dongle. If someone has more experience reporting bugs to the kernel developers, he should share where and how I can report it

Cheers!

Actually the problem didn't stop after my last fix. So after more investigation I found this - https://bugzilla.kernel.org/show_bug.cgi?id=200977

Now it seems the r8152 kernel module causes the issue. I have recompilled this driver - https://github.com/wget/realtek-r8152-linux but the problem is still not resolved.

Any ideas what I can try next? I really want to use this hub - it's too convenient.

Thanks!

I just fixed a problem I had with printers not being recognized if plugged to a C hub. Solution was to use an adapter C to A and plug an A hub to it, OR get a different C hub. In this case I switched from an Inland to a Aluratek C hub. In any situation things worked perfectly in win10 but I had to get a different hub to make it work in Mint. No clue as to why.

https://bugzilla.kernel.org/show_bug.cgi?id=200977#c42

It seems that the issue is gone in kernel 5.14

To install it on Mint 20.2 I added this ppa - https://launchpad.net/~tuxinvader/+arch ... s-mainline and installed linux-generic-5.14

Cheers

[Kris345]

That's good to hear. Thanks!
