On my machine with BT moudle 8087:0026, I reproduced the problem, and
replaced with 20.10 firmware ibt-19-0-4.sfi, but still could not work in
hsp/hfp mode.

What I found is the bt driver can't receive the SCO packet, the returned
packet length is always 0.


And if the bt headset can't work in the hsp/hfp mode, please run hci config, if 
the output like below (RX bytes: sco:0 TX bytes: sco:1), that means the bt 
driver can't receive SCO packets, as a result the headset can't work in hsp/hfp 
mode since hsp/hfp mode depends on SCO link.

hci0:   Type: Primary  Bus: USB
        BD Address: D4:D2:52:3D:49:E6  ACL MTU: 1021:4  SCO MTU: 96:6
        UP RUNNING PSCAN 
        RX bytes:23638 acl:85 sco:0 events:3463 errors:0
        TX bytes:980646 acl:323 sco:1 commands:3121 errors:0
