Does anyone know of a registry setting to make the SD card on an ES400 persistent? i.e. Does not unplug/replug when the terminal suspends/resumes. Available on other terminals. Is it available on the ES400?

Richard,
ES400 OEM 19.1 and MC65 OEM 21 unload the SD card on suspend-resume. CQ29005
Note: below regkey change keeps the SD card powered-on in suspend but has the downside of add 1 mA additional power draw in suspend.
