I installed DSL to my USB stick following the pendrivelinux guide, but when I boot it says: Can't find KNOPPIX filesystem. + something about going into a very limited shell. Also, I try pressing Enter (to proceed), but my keyboard doesn't work. (when I try to write something in the writable screen I get it doesn't write.) Do I need a driver for my keyboard (Logitech Internet 350) or is it a incompatibility with FAT32 or my hard disk's NTFS?
