I have a device, custom mp3 player, that the pid and vid show up as a011:a011.

I can connect to this device in windows 7 by selecting a generic mass storage device driver. It has a single fat32 partition that I can read and write to.
My system is Ubuntu 14. Every thing works. I connect a USB thumb drive and it auto loads the driver and creates the /dev/sdX
point.
How do I connect this mp3 player to my linux pc. If I can create the /dev/sdX
point then I can mount it.
I have been reading and trying to use modprobe and creating a /etc/udev/rules.d/80-mp3_a011.rules
, but It has not clicked yet.
I would like to connect a single time via the command line first.
Next I would like it to connect every time I plug it in.
Last using this information I will create the rules for mdev that I use on my embedded system.

Got the second part working.
"Next I would like it to connect every time I plug it in."
Created a udev rule at:
Added this info that simply modprobes usb-storage and adds my pid:vid to the usb-storage new_id.
restart udev
Now as soon as I connect the device it is handled like any other usb mass storage device.
First part working:
"I would like to connect a single time via the command line first."
Did NOT work because the sudo was applied to the echo command and not the new_id file, or some such thing.
Changed to a root shell first then added the PID:VID to the new_id.
