The microSD works fine in some other Linux laptop;
The FR's card reader or the Om2008.9 kernel can't read this microSD,
it gives on boot

sending read/write command
and as well I can't read the block 0 with dd(1);
another microSD of 4 GByte of a colleague works fine in the Om2008.9:

I will buy a new one.
