+STM8S-Discovery:
+----------------
+
+SUBSYSTEMS=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="3744", MODE:="0666", GROUP:="dialout", SYMLINK+="stlink_%n"
+
+The discovery board also emulates an USB mass storage device. However the
+implementation is buggy and it doesn't really work with linux. It's best to
+just ignore the usb-storage endpoints. You can do this temporarly using the
+following command:
+
+  # echo "0483:3744:i" >/sys/module/usb_storage/parameters/quirks
+
+To make this permanent, create a file '/etc/modprobe.d/stdiscovery.conf' with
+the following content:
+
+<snip>
+options usb-storage quirks=0483:3744:i
+</snip>
+
+The changes will take effect on next reboot or after manually unloading the
+usb-storage driver
+
+  # modprobe -r usb_storage
+
+This might not work if there is another device connected that is or emulates
+an USB storage device.
