LogiLink UA0053 USB sound card

This is to record the fact that LogiLink UA0053 USB sound card (audio adapter) works out of the box with Linux Mint 18.

Just remember to go to Sound preferences and tell the system to play music via your new sound card (if needed).

Canon LiDE20 not working

So you have a new computer with those blue USB3 ports and are using probably Linux Mint 17.3 Mate, Ubuntu 14.04 or similar OS.

The Canon LiDE20 scanner which used to work with your older computer, refuses to scan now.

If you enter “scanimage -L”, you get output shown here below, followed by a long wait:

  • device `plustek:libusb:002:003′ is a Canon CanoScan N670U/N676U/LiDE20 flatbed scanner

The problem is related to the fact that your system has USB3 ports.

One way to solve the problem is to go to BIOS setup of your computer and look for USB ports related options.

With my ASUS motherboard I fixed it like this:

  1. F2 or Del at boot for BIOS setup
  2. Advanced Mode (F7)
  3. Advanced:
  4. USB Configuration:
  5. Intel xHCI Mode -> change from Smart Auto to Disabled


Screen tearing in Linux Mint

Pronounced screen tearing with Linux Mint 17.3 Mate (inherited from Ubuntu 14.04).

Solution is extremely easy.

Create the following file:

  • /etc/X11/xorg.conf.d/20-intel.conf

And enter the following content:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "TearFree"    "true"

Connect Nikon D3300

You connect your Nikon camera to your Linux box and nothing happens. It isn’t recognized and it isn’t attached as a mass storage device.

Well, try a different approach. Instead of trying to connect to it as if it were a disk, try to use PTP (Picture Transfer Protocol) enabled software to get the images.

Create a directory for you pictures, change into it, then run:

  • gphoto2 –get-all-files

Note: It is two short dashes, not one long dash before get-all-files. Page formatting seems to change that.

USB cable for Nikon D3300

For DSLR Nikon camera D3300 the proprietary standard USB cable is model UC-E17.

But you can use model UC-E6 with equal success, at least for image transfer.

Mount Nikon DSLR camer via PTP on Linux

Install gphotofs, then create mount directory, e.g. /media/NIKON

To mount:

  • gphotofs /media/NIKON

To unmount:

  • fusermount -u /media/NIKON


Another way to get pictures is without mounting. First install gphoto2, then:

  • gphoto2 –auto-detect
  • gphoto2 –list-files
  • gphoto2 –get-all-files

Lenovo B50-70 factory reset from recovery partition

To run a factory reset of Lenovo B50-70 from the hidden recovery partition:

  • Switch off the laptop.
  • Look for a small pinhole at the right side of the laptop, between the single USB port and the CD-DVD drive, closer to the USB port.
    At the first glance you may miss it, thinking that it is a kind of a LED indicator or even a miniature socket for earphones, as the OneKey Recovery symbol is very small and reminds of the headphone symbol.
  • Take a pointy object, preferably non-conductive one, e.g. a toothpick, insert it into the pinhole and gently push it. You will feel the miniature switch click. Keep pressed for about 2 seconds, then release and wait.
    The laptop then will switch on and boot into the special “Novo Button Menu” (its those  marketing people again…).
  • Select the “System Recovery” option and proceed in accordance to the instruction on the screen.


I just wonder why those geniuses at Lenovo could not think of providing a simple and clear information on where to find the reset button. You can spend half a day reading manuals and calling up tech support, before you find it out.

It said nothing about the pinhole in any of the Lenovo manuals I read and the only information about it at the laptop itself was a marketing sticker boasting this function, without telling how exactly to activate it, only warning that “Some features are only available while running Microsoft Windows”, which does not help you much when your Windows has become unusable.

Go figure…
