The log file doesn't show any errors. Please enable CONFIG_PRINTK_TIME in the configuration, and before starting the test do: rmmod ohci-hcd echo -n sb_07 >/sys/bus/bus/usb/devices/usb4/../driver/unbind (That second line will disable the Bluetooth controller.) Then run the same test again, this time reading data from the headphone.
