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

Jan 11 13:12:21 om-gta02 user.err kernel: [    3.320000] mmcblk0: error -110 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:  

Jan 11 13:31:22 om-gta02 user.debug kernel: [    1.955000] mmc_set_power(power_mode=1, vdd=20
Jan 11 13:31:22 om-gta02 user.debug kernel: [    2.825000] mmc_set_power(power_mode=2, vdd=15

Jan 11 13:31:22 om-gta02 user.info kernel: [    3.460000] mmcblk0: mmc0:0001 00000 3849216KiB 
Jan 11 13:31:22 om-gta02 user.info kernel: [    3.465000]  mmcblk0: p1

I will buy a new one.
