I’ve seen issues reported from various people here about the AMD (aka Mediatek) Bluetooth having issues upon resume. I’ve very occasionally experienced issues with my BT mouse (Logitech MX Master 3) on my 7040 FW13 laptop upon resume. Can’t say I’ve seen this with other USB devices, but I’ve seen people report problems with e.g. the fingerprint reader in addition to/instead of BT - when resuming from s2idle.
So anyway, I just saw this patch fly by on the bluez list:
Remove the resetting step before downloading the fw, as it may cause
other usb devices to fail to initialise when connected during boot
on kernels 6.11 and newer.
I won’t have time to build a patched kernel any time soon, and anyway problems only reproduce for me very sporadically, so maybe someone who can reproduce more reliably could try this.
