[SOLVED] USB keyboard and mouse not detected

[SMG]

Are these USB devices very new? What brand name is on the hub? It might be possible that the linux drivers available for them may not yet be the best match.

Are these USB devices very new? What brand name is on the hub? It might be possible that the linux drivers available for them may not yet be the best match.

Before I do that the reminder: The unplugging and re-plugging issue persists with and without USB hubs and on any USB port both 2.0 and 3.0. So...

• Atolla USB 3.0 HUB
• Sabrent HB-UM43 USB HUB
• Wacom Intuos S
• Sharkoon Skiller Gaming Keboard
• Zelotes T-80 Gaming Mouse

I bought all devices in the last 5 years, but I have to check how old they are exactly...

[Akura]

Okay... quick update... My computer is on for about an hour and the keyboard is still working. I'm cautiously optimistic...

Yesterday I changed the

Code: Select all

/etc/default/grub

file to have the line

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1 iommu=soft"

and then I updated the grub. I already did that several days ago, but back then there were a couple parameters more which were suggested by some Google results. Yesterday I then tried several combinations of these parameters and the ones above seem to work for now. It somewhat makes sense that there is a problem with auto suspension, but, interestingly,

Code: Select all

usbcore.autosuspend=-1

alone didn't work.

Let's see how it looks tomorrow. Waiting for nothing to happen is a bit annoying...

Good luck and kudos for your saint level of patience dealing with this annoyance.

The person in this thread, Solved Lost USB devices after Mint 20 installation ended up reinstalling Mint several times and then finally everything worked properly. The problem might be a little different than yours, but just wanted to make this available if your current fix does not work.

Ah, yes, I saw that thread! But I didn't read the "conclusion" yet. Re-installing the OS often helped me in the past, but I don't want to go there unless it's absolutely necessary.

So, after a morning of several hours of work and a longish video call, everything works. I conclude that changing the grub file did fix the problem. For now...
Thanks again to everyone who offered solutions!

Just out of curiosity, please type "sudo update-usbids && sudo update-pciids" at the terminal command prompt, to update your system's USB and PCI device identification databases. This should look something like this ...

Code: Select all

$ sudo update-usbids && sudo update-pciids

@hglee: To help Akura, if his version of Linux Mint 20 has usbutils installed, but doesn't have update-usbids, is there a manual method to perform the update?

For example, would the following work?

Download the file

Code: Select all

curl http://www.linux-usb.org/usb.ids > usb.ids

and then execute the following:

Code: Select all

sudo mv usb.ids /var/lib/usbutils/usb.ids.new
sudo chmod 644 /var/lib/usbutils/usb.ids.new
sudo chown root:root /var/lib/usbutils/usb.ids.new

Or should the existing usb.ids file be replaced by the updated file?

I checked 3 Linux Mint 20 Cinnamon machines, and they don't have update-usbids but they do have usbutils installed. They do have update-pciids.

Edit: Looks to me like it should replace it...

Would probably need to first verify the contents of the new file first to ensure it wasn't clobbered when downloaded, and then run something like...

Code: Select all

cd /var/lib/usbutils
sudo mv usb.ids usb.ids.old
sudo mv usb.ids.new usb.ids

EDIT2 NOTE: Probably need to use a program like geany to view and check the contents of usb.ids. Other text editors might give problems.

Further research indicates that the script may have been removed on purpose from usbutils. Some people consider it dangerous to modify files outside of user areas, and some people have questions regarding this update.

Yes, these commands should do what update-usbids does ...

Code: Select all

wget -c http://www.linux-usb.org/usb.ids
sudo mv --force ./usb.ids /var/lib/usbutils/
sudo ln -sf /var/lib/usbutils/usb.ids /usr/share/misc/usb.id

For repetitive convenience these commands may be placed into a script named update-usbids and placed in the ~/bin directory after doing chmod +x update-usbids ...

Code: Select all

#!/bin/bash
## name this script as 'update-usbids'
wget -c http://www.linux-usb.org/usb.ids
sudo mv --force ./usb.ids /var/lib/usbutils/
sudo ln -sf /var/lib/usbutils/usb.ids /usr/share/misc/usb.id
exit

Of course, this action doesn't download any drivers, so it doesn't fix anything -- but it updates the system's USB ID database so that lsusb may offer something more informative than device "ID 046d:c52b".

@hglee -- Thanks! Perfect!
