User-facing symptom is = that BLE mouse and keyboard become difficult or impossible to connect while Chro= me is open; closing Chrome often allows reconnect. This appears to be a kernel or controller stability problem, potentially amplified by power management settings and high USB activity. ## Environment - Distro: ArchLinux rolling - Kernel: 6.19.14-zen1-1-zen - Bluetooth controller: Intel AX211 Bluetooth (USB ID 8087:0033) - Devices affected: Logitech M720 mouse, Logitech K850 keyboard (BLE HID) ## Reproduction 1. Boot system normally. 2. Ensure Bluetooth service is active. 3. Open Chrome and use system normally. 4. Attempt to connect or keep connected BLE keyboard and mouse. 5. Observe failures, reconnect loops, or failed writes. 6. Close Chrome and retry; connection usually succeeds. ## Expected behavior BLE mouse and keyboard should remain stable regardless of Chrome state. ## Actual behavior BLE HID profile operation intermittently fails; reconnect loops occur and controller errors are logged. ## High signal evidence >From kernel log: Bluetooth: hci0: Hardware error 0x0c Bluetooth: hci0: Retrieving Intel exception info failed (-16) >From bluetooth service log: profiles/input/hog-lib.c:output_written_cb() Write output report failed: Request attribute has encountered an unlikely error Wrong size of start discovery return parameters Power-management related state on this host: /sys/module/btusb/parameters/enable_autosuspend=3DY /sys/module/usbcore/parameters/autosuspend=3D2 ## Attachments - System snapshot: ax211-bt-system-2026-04-27.txt - Log highlights: ax211-bt-logs-2026-04-27.txt --=20 You may reply to this email to add a comment.
