--- Comment #77 from Swyter (swyterzone@gmail.com) ---Still having the same problem on Linux 5.7.4. 75.58, in my case it's one of these super common, round, unmarked dongles: https://web.archive.org/web/https://pl.aliexpress.com/item/33058605031.html Here's what running `hcidump -X` while doing `hciconfig hci0 up` shows; it errors out while trying to delete the stored link key. So, same problem and different bcdDevice; 75.58, sounds like someone needs to add a bunch of extra quirks: HCI sniffer - Bluetooth packet analyzer ver 5.54 device: hci0 snap_len: 1500 filter: 0xffffffffffffffff

This is my `uname -a` shows. I'm just running the normal Arch Linux kernel:

Seems like they have stolen bdaddr space from 00:15:83 IVT corporation. Anyway,
hope that helps, let me know if anyone needs something else to diagnose to test
a proper Kernel patch that gets mainlined. I'm all ears. :)
