I'm not familiar with using barcode readers on Linux, so my help will be a little limited.
It looks like this device is handled by 'btusb' so you have to have the module included. It is possible you do not as I would expect some related log messages to appear.
There may be firmware involved. May work without, but hard to say. Firmware is probably proprietary and not part of Thinstation.
Start there and let us know what you get.
My next worry is whether the scanner remains paired to the USB dongle or if something has to be configured every time the system reboots. I've successfully used some Logitech mice/keyboards with USB BT dongles without adding any pairing tools to TS.
