--- Comment #8 from Hans Petter Selasky <[email protected]> --- Hi, I see in the log there is a problem with the XHCI controller, not the Focusrite. 19:56:09.868398 usbus1.2 DONE-ISOC-EP=00000001,SPD=HIGH,NFR=0,SLEN=0,IVAL=0,ERR=TIMEOUT It looks like it didn't generate a completion event for an isochronous job, so the isochronous schedule stopped feeding audio. Try to build a new kernel with: options USB_DEBUG added to the kernel config. Then set for example: sysctl hw.usb.xhci.debug=17 sleep 10 sysctl hw.usb.xhci.debug=0 Then repeat the test and collect logs from /var/log/messages --HPS -- You are receiving this mail because: You are the assignee for the bug.
