How to recover data from damaged device thru USB

Dear Expert,
I got a real tough problem with my Asus-Zenfone-5 Android device.
The device had got badly damaged and the only thing it is willing to do now is to show on screen the charging process sign (A battery icon) when the cord is pluged to ELECT.
When I connect the device by USB to my pc It doesn't recognize it at all and Showing "Unknown device" at that certain port.
Could anyone Help me please in getting my data out of this device?
Thanks a lot
Yossi
