+1.1 Troubleshooting
+~~~~~~~~~~~~~~~~~~~
+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
+ instructions provided by your distribution on module configuration.
+
+Q: Phone is working now (displays version and accepts keypad input) but I can't
+ find the sysfs files.
+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.
