Review on Edimax BT 5.0 EDR Nano USB Dongle for PC - Fast Transfer for Bluetooth Headsets, Speakers, Keyboards, and Mice - Compatible with Win 8/10 and Linux 2.6.32-5.3 (Fedora & Ubuntu) - BT-8500 by Jacob Mayberry

Bought because a reviewer said it works out of the box with Fedora 33 kernel 5.9 (review was about a month old when I bought this product). Now on kernel 5.10 and absolutely doesn't work on Fedora 33 with kernel 5.10. Another reviewer on Fedora 32 said that he/she was having random timeouts and that his/her bluetooth device was never fully connected. That's exactly what I'm experiencing. The drivers provided by EDIMax come in zipped form with source code and installation instructions are minimal. They say they support a kernel version up to 5.3, which only works on Fedora if you have an end-of-life version (probably Fedora 31 or 30). It might work one day, but a vendor shouldn't claim to support Fedora if they don't want to keep up with kernel releases. Not recommended for Linux users. Use this device at your own risk.
