The systerescue-cd has 4 kernels: 2 * 64bit and 2 * 32bit. By default, it boots the "default" one for the architecture you are booting. Have you tried booting the "alternate" kernel? I have 1 system that I need to boot using the "alternate" kernel as the "default" one is too old. (Yes, by default it boots an old kernel) It could easily be that the kernel you are using does not support your USB3 adapter or something else you used. Eg. apart from all the 'ls' statements, also check "uname" and "/proc/config.gz" for differences. -- Joost
