You have to run lsusb -t to get full tree of USB hubs.
Below is the example from my USB 3.0 capable laptop:
$ lsusb -t
/: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 5000M
|__ Port 2: Dev 6, If 0, Class=Mass Storage, Driver=usb-storage, 5000M
/: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 480M
|__ Port 1: Dev 3, If 0, ...

So as of writing this, the reason for the lack of support for USB serial devices is due to their modules not being included in the WSL kernel.
You can compile your own WSL kernel with the modules by doing the following:
You may need these dependencies: sudo apt install build-essential flex bison libssl-dev libelf-dev dwarves libncurses-dev
Clone the WSL2 ...

The command sudo lsusb -v lists significant information about connected devices including speed capability. (Although I'm not sure if it lists actual speed.)
The sudo usbview command is a graphical browser, and one of the top items in its list seems to be the current speed of a device.

After all the problem was the Fast Boot of the bios: SecureBoot (Disabled) AND OS Mode Selection (CSM OS).
Thank you all for helping me solving this mystery.

Booting ISO from GRUB Menu
The method on this page should work for booting an Ubuntu ISO from the GRUB bootloader 20.04 booting .iso from GRUB menu No need for a USB here.
To reiterate:
Add the following menuentry to /etc/grub.d/40_custom:
menuentry "isoname ISO" {
set root=(hdX,Y)
set isofile="/[path]/[isoname].iso"
loopback ...

Considering that OP is not providing a lot of details about the nature of their error, I'm going to assume that they were expecting that, once Rufus was done creating the media, Ubuntu would automatically boot.
Well, that's not how it's designed to operate, because Windows and Ubuntu cannot coexist (outside of using a Virtual Machine or WSL, but if you're ...

It, most certainly, is possible to change both the description and serial number (which is used for the name listed in /dev) in the EEPROM of the FTDI chip - at least on OS X - which should also show up in Ubuntu.
Note: I've not been able to check it as my Ubuntu box has just suddenly died (PSU failure)..!
This method uses an application for OS X, so there ...

A setting on the phone governs how the computer interacts with it. On my Android 10 phone it's under Settings > Connected devices > USB preferences > File transfer.
Note that to see the USB preferences, it appears that you have to have a USB cable plugged in.

No. You can't. It's hardware that is missing. USB C on many laptop supports USB C Alt mode which is DP over USB C cable.
The sound is however a normal USB signal, and thus works perfectly fine over USB.

You can tell the mount point in /etc/fstab.
So you would set the name, and your partition would always mount with the same name.
The header of the file is reasonably explanatory
$ cat /etc/fstab
# /etc/fstab: static file system information.

# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust ...

Please try:

The issue disappeared after I switched back to X11...
sudo nano /etc/gdm3/custom.conf
and uncommented
WaylandEnable=false
After that
sudo service gdm restart
login to Ubuntu or Gnome session, and verify that the session is X11 indeed
echo $XDG_SESSION_TYPE
x11
in my case, I also had to remove the old ...

I resolve it. I reinstalled the driver with this commands:
sudo apt install git dkms
git clone https://github.com/aircrack-ng/rtl8812au.git
cd rtl8812au
sudo make dkms_install
If you don't hace permission try to execute:
chmod 777 rtl8812au

This is the issue. Behringer u-phoria umc204hd has 4.0 audio - 2 separate stereo channels, but then using phones, you can get only one of them. While other apps play in both, Telegram plays only in one of them. So to fix that, you just need to switch output in phones by pressing Monitor A/B switcher on the device

It is hopeless.
Your USB C dock expects a video signal over the USB C cable, but your USB A to C adapter only repeats the USB 2.0 signals. Some also handle USB 3.0 signals.
To make your dock work, you have need an USB A to C adapter which has a graphical card build in to re-create the missing video signals from a standard like displaylink. If these would ...

10-gesture.rules 10 is very early for such devices and this rule just to create simlinks.
Try using high number 90~99 only if you know rules that you want to override (fully or partially) or influence its actions later)
udev support variable substitution, so you could use some attributes in symlink name. Otherwise, create a script that verify previous ...

Now we talk about the github version of woeusb
The github version is at 5.1.3 and works in Ubuntu 20.04.x LTS (and 18.04.x LTS, probably all current versions of Ubuntu, but I have not tested them).
PPA version of woeusb deprecated
Please be aware that the woeusb PPA version at ppa:nilarimogard/webupd8 is deprecated (works in Ubuntu 18.04.x LTS but fails in ...

The power usage of a USB device is not likely to change because it was moved to a different port. What is far more likely is that the reporting of the power consumption changed by moving to a new port. A charging USB port will have to make a larger power budget allocation if anything is detected on the port as a device that is charging from USB doesn't ...

Don't forget to disable Secure Boot (UEFI) if you have it enabled.
Here's a guide:
