It is not a kernel problem. Thanks, I can reproduce the issue using kernel 3.9.9 and $ sg_inq -l 512 /dev/sdb I am guessing that this is the reason for the suspend/resume issues with 3.9 and 3.10 as well. A look at the program's code might reveal why this was not triggered on 3.9 and 3.10 as bad as on 3.11... -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
