journalctl: what does “New USB device found” mean?

Aug 17 02:16:44 <hostname> kernel: usb 1-2: new high-speed USB device number 13 using xhci_hcd
Aug 17 02:16:45 <hostname> kernel: usb 1-2: New USB device found, idVendor=05c6, idProduct=aaff, bcdDevice= 3.18
Aug 17 02:16:45 <hostname> kernel: usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
Aug 17 02:16:45 <hostname> kernel: usb 1-2: Product: Android
Aug 17 02:16:45 <hostname> kernel: usb 1-2: Manufacturer: Android
Aug 17 02:16:45 <hostname> kernel: usb 1-2: SerialNumber: 0123456789ABCDEF

Above is a snippet from my journalctl output. Are entries stating new USB device found... a log entry of a USB device being plugged in to my system? I didn’t plug any USBs today. So was wondering if this could be something worrying as someone else trying to access my computer when I am away?

TIA!

LUbuntu (L ubuntu) 20.04 screen/display colour calibration how to?

I recently installed LUbuntu 20.04 (UEFI-GPT) dual boot with Win10. (check screenshot attached).

I’m not able to change the color scheme of my display as I can’t find my graphics card control panel program(Intel Graphics Control Panel/AMD Radeon Software) to do so. My screen in more blue in color..and it’s restraining my eye. I’m not getting natural screen color as I used to get in Win10. (blue tint isn’t visible in screenshot)

Prerequisite : I’m noob in Linux world, I appreciate your help and time.

thankyou

How can I install more than one Desktop Environment in my Ubuntu without damaging the system?

How can I install more than one Desktop Environment in my Ubuntu without damaging the system? I want just to try those desktop. I know I can install them by sudo apt install kubuntu/xubuntu/lubuntu-desktop . But it will remove my existing Desktop Environment, right? I want that whenever I want to change the Desktop Environment, I will log out and log in to that. Is it possible to do that? Don’t say to download ISO image of Kubuntu, Xubuntu, Lubuntu as I want to see them in my current installation.
