hap, there seems to be a problem with the NVRAM of the Saitek Turbo King (ver. D).
All other machines of this group (tkinga, tkingb, stratos, stratosa) remember changed settings (e.g. the level) when you start them the next time, but tking forgets everything.
It also makes the LED check at every start, whereas all other engines do this only at the very first start (if no NVRAM is saved yet) - also a sign of a not correctly working NVRAM in tking.
