0x5103 is not in the list:
<https://github.com/torvalds/linux/blob/master/drivers/media/dvb-core/dvb-usb-ids.h>
It's likely not supported.
You can try to find a separate driver. 
You can try to figure out the chipset and load a driver if one already exists. 
You'll have to alter the drivers product id so the kernel will be able to use 
the driver with your device.  

You may want to watch this video:

Or you throw that stick out the window....
