Bonjour.
Depuis le noyau 2.6.37 , les ports usb ne marchent plus. J’espérais une amélioration avec le 38, mais en vain.
Voici ce que me dis le système :
dmesg | grep -i usb

Les sujets en lien que j’ai trouvé sur la toile ne parlent que de recompiler le noyau, chose que je ne sais pas faire et que j’aimerais autant éviter…
Des idées?
. PArce que là, j’en ai marre
