As far as I can see you have the following situation
I guess the turntable has a moving magnet cartridge which will give an output of around 5.5mV ......................Now the standard non phono input requires around 150mV to work. This will explain why you will only get a sound at the top of the volume control.
The USB turntable idea is to have a pre amp in it to boost the voltage from 5.5 to around 150 mV . My guess is that the turntable will have to power the pre amp somehow as you can not get something for nothing. So I guess that there should be a battery in the turntable somewhere and this is the problem. If you can locate where and put in the battery , this should solve the problem. Having read the specification of the turntable I see that the phono pre amp is "Selectable internal stereo phono pre amplifier" in which case you may well have to find out how to turn it on ..................somewhere there should be a switch!

Nice to be able to go back to trust and friendship!!!!!!!!!
It's a mixed up sensation this being alive
Oh! it wears a man down into the ground
It's the strangest elation
I can't describe it
Oh it leaves a man weary
It makes a man frown..............................Chris Simpson ( "Mixed Up Sensations" 1975 Martin's Cafe )
