+  <code>CULflash &lt;CUL-Name&gt; &lt;CUL-Version&gt;</code> <br>
+  <br>
+    Download the CUL firmware from a nightly CVS chekout and flash the
+    hardware. Currently only the CUL is supported with its versions:
+    CUL_V2, CUL_V2_HM, CUL_V3, CUL_V4.<br>
+    <b>Note:</b> dfu-programmer has to be installed in the path.<br>
+    If the CUL is not yet flashed, then first define a <a href="#CUL">CUL</a>
+    device (even if fhem won't be able to open the device), insert it with the
+    button pressed (this will set the device into flash-mode), then issue the
+    CULflash command.<br>
+    Example:
+    <ul>
+    <code>fhem> CULflash CUL CUL_V3</code>
