Comment 58 for bug 1871794

Update:

If the bluetooth module is 8087:0029 or 8087:0026, the firmware in the 20.04 has some problem, we need to update the firmware, and I found the most import is *.ddc instead of *.sfi,

For 8087:0029, please update ibt-20-1-3.sfi and ibt-20-1-3.ddc from 20.10 or latest upstream

For 8087:0026, please update ibt-19-0-4.sfi and ibt-19-0-4.ddc from 20.10 or latest upstream

After update, please poweroff the machine (not reboot), this could guarantee the bt driver will reload the firmware (sfi and ddc), then power on the machine, test the hsp/hfp mode.

I have tested, after update the ddc, hsp/hfp could work with 8087:0029 and 8087:0026 now.
