You don’t really need the USB Dongle.
Wireless fitting - FittingLINK
FittingLINK provides a wireless link (Bluetooth) between the PC
and one or two wireless enabled hearing instruments. In addition
FittingLINK can be used via a USB cable connected to the PC.
Tip: If you also have the ability for selling your Alta’s in the future, perhaps you could keep an eye out for upgrading to a pair of OPN 1’s for $300 or so (Not to be confused with OpnS 1s).
You’re ignoring this member’s posts.

. My laptop using a USB Bluetooth 5.1 dongle can only pair to the FittingLink but never connect to it. The USB 2.0 cable does work and detects the FittingLink. Here is my experience.
