Si, après introduction de la carte dans le lecteur interne du PC, je fais
tail /var/log/messages
(sans l'argument "-f" qui fait boucler le programme et ne permet pas le retour du terminal à #),
[root@localhost ~]# tail /var/log/messages

la ligne la plus significative est
sdhci: Switching to 1.8V signalling voltage failed, retrying with S18R set to 0
Dans Google, la recherche de cette phrase donne 6 pages de résultats dont :
https://bugs.launchpad.net/bugs/910835
avec un patch correctif :
https://bugs.launchpad.net/linaro-landing-team-freescale/+bug/910835/+attachment/2663626/+files/0001-mmc-sdhci-esdhc-imx-support-of-1.8V-is-board-specifi.patch
Quelqu'un a-t-il une idée de la façon d'impléménter ce patch ?
PS - Si j'insère cette carte dans un lecteur de carte USB, elle est parfaitement reconnue et lue

C'est quand même idiot de devoir utiliser un lecteur USB quand il y a un lecteur intégré !
