Description Mark Herbert 2024-10-14 08:19:46 UTC 
Installsed 6.12-rc3 and lost connection to BT mouse. Deleted it in blueman and tried to pair again - scan shows some devices around but not mice (tried alternative mice - huawei CD23 and Lenovo) with the same result.

Reverted 	610712298b11b2914be00b35abe9326b5dbb62c8  - Bluetooth: btusb: Don't fail external suspend requests

with this commit reverted mouse is available again with no issues

Mark, thank you for the report. There are two more reports on the list with the same findings as you:

1.  Connection issue since 81b3e33bb054 ("Bluetooth: btusb: Don't fail external suspend requests")
2.  Commit 610712298b11 ("btusb: Don't fail external suspend requests") breaks BT upon resume on my laptop

I think, the plan is to revert the commit.

I've also been having some problems with BT connectivity after installing 6.11.4. I'll test the above patch and report back in a few.

I can confirm that the mentioned patch restored typical connection behaviour for my BT keyboard and earbuds.

I have the same problem here, on an Acer Swift SF314-54-53QH. According to lsusb the affected material is : "ID 8087:0a2a Intel Corp. Bluetooth wireless interface". The mouse trying to connect is a Logitech M240. But it looks like the bluetooth controller is unable to scan its whole environment.

I have NOT the problem with another laptop (Dell Latitude 7490) which connects with a mouse of the same brand (Logitech M240). The bluetooth controller is nearly the same but slightly different: "8087:0a2b Intel Corp. Bluetooth wireless" (note the different product identifier).

Note: I have the problem starting with Linux-6.11.4 (Archlinux flavor) so for now I stick with 6.11.3.

Confirming that this patch applied to 6.11.4 also fixes bluetooth on my Intel AX210.
