"image is dark" means the image is OK and just too dark, or is it completely black?
Then this sounds like https://bugs.mageia.org/show_bug.cgi?id=21244 which seems to be a problem with an USB 3 port, and the same scanner works with an USB 2 port.

Do you have a non-USB3 port on your computer?

That is also mentioned in the linked bug report(s). lsusb -t should also show it.

It seems I only have non-USB3 port.

Hm strange. 12M is actually USB 1.1 speed. https://en.wikipedia.org/wiki/USB
My USB2 hubs get listed at 480M and my USB3 at 5000M
what do lsusb without "-t" tell?

Shooting in the dark as i do not know these matters...
But USB1.1 is probably slow to use if it even works so first make sure it is on a USB2 port...
I dont know off hand how to tell what port the scanner is on, but "lsusb -v" may give a lead, and also watch system log while you plug it in:
I.e in konsole log in as root and issue "journalctl -f", then plug in your scanner and watch it being detected as USB device.
