My help here will be general, because I have no experience with this.
But a fingerprint reader is just an IO device, right? So I'd use lshw to find specific info on that IO device, and then make sure I had the right drivers for that specific IO device.
If you've already done that, then I'm no help :)
The links you posted suggest there is no driver available for your fingerprint reader on Linux. If this is correct, you can't use it, as without a driver the operating system doesn't know how to communicate with the device.
As a side note, apart from Android devices I've never had a working fingerprint reader on Linux.
I ran into the same issue on my ASUS laptop but was never able to get it working.
Don't waste your time. Even if you manage to get the sensor to work, you'll only be able to like log in.
