Hello Ceel,
first I tried to install Slitaz from the panel. When i get to the step of choosing the medium from which install, i can only choose SDB (error-1.png) whereas the USB stick I have SliTaz on is /dev/sdb1.
I also tried tazweb-installer from the terminal.
There i get first the right USB identification (error-2.png) but then I get an error message (error-3.png).
As for the fdisk and blkid output they are:

I burned the .iso image on the USB stick with dd as usual, so I assume the reading should be fine.
Copying the .iso on the home dir of the live CD and choosing install from .iso on the installer menu worked just fine.
I hope it helps.
