+Q: Module yealink compiled and installed without any problem but phone
+   is not initialized and does not react to any actions.
+A: If you see something like:
+   hiddev0: USB HID v1.00 Device [Yealink Network Technology Ltd. VOIP USB Phone
+   in dmesg, it means that the hid driver has grabbed the device first. Try to
+   load module yealink before any other usb hid driver. Please see the

+Q: Phone is working now (displays version and accepts keypad input) but I can't

+A: The sysfs files are located on the particular usb endpoint. On most
+   distributions you can do: "find /sys/ -name get_icons" for a hint.
