Retrieve pictures from Samsung cellphone
My Samsung Brew cellphone takes good pictures and is handy when I'm in the middle of a project, but I haven't solved the problem of transferring the images to my Trisquel 7 installation on a Lenovo T420 without having to resort to restarting it in Win 7 to get the files onto the Win 7 portion of the hard drive, restarting into Trisquel, and moving the files to the Home directory.
Trisquel has no problem detecting the cellphone:

BTW, there's no disk in the Samsung CDROM drive at the moment.
Yes, the flash card in the cellphone is one GB ... and the cellphone's Model No. is detected correctly.
Win 7 has no issues with detecting the flash card and downloading images or video.
I created a mount point: /mnt/Samsung-SCH-U680 but I haven't guessed the right /dev/*.* to mount, as everything I've tried fails, such as mount /dev/sdb1 /mnt/Samsung-SCH-U680.

[scsi 6:0:0:1: Direct-Access SAMSUNG MMC Storage 2.31 PQ: 0 ANSI: 2]: Is this the RAM in the cellphone ?

Apparently, Trisquel doesn't like sdb and is getting I/O errors for some reason.
If the phone has a removable storage card you could try to remove it and mount it directly. Your computer may have a built-in card reader or you may need to get a USB card reader.
In the past I did exactly that, but the cheesy adapter was showing signs of wearing out, so I decided to use the original charger/USB cable instead, because it's better made. Maybe someone here can suggest a USB adapter that will work reliably. As an example, I have an old Dell Inspiron laptop whose built-in card reader broke before all the other parts of the machine started falling apart ... which inspired me to switch to my present Lenovo T420 with this forum's excellent advice.
Have you written a udev rule file for your phone? It appears to be missing,
from the logs you posted. I had to add my phone vendor ID and other information
to udev to get App Inventor to connect to my phone. There are some instructions
for writing rules here: https://developer.android.com/tools/device.html. The
section 'set up your system to detect your device' is most helpful. Try that.
See the first few lines of my first post:

That's exactly what the ID card of my phone says (underneath the phone's battery).
At the phone end, when I plug in the USB cable, I am presented with a choice between charging the phone's battery or doing a USB transfer. The phone continues to present itself for access when I try everything I can think of with the terminal to find out where in /dev/ the blasted thing is located ... dmesg seems to be telling me it's in several places at once while the error messages tell me that the mount command isn't finding anything at those places.
The USB card adapter has no trouble whatsoever mounting & moving files in & out of the card with linux.
I have given up on waiting for a solution for this issue of establishing a working cable connection between Ubuntu or Trisquel and Android. Thus, I usually just use Airdroid (https://www.airdroid.com/) these days. It just works and I don't have to deal with this buggy mess...
On the pro-side I also don't have to install any non-free software on my Trisquel machine as I can just open a web-browser there.
There's no history of Samsung Brew SCH-U680 in the AirDroid forum ... and no sign of a linux connection in the downloads offered ...
