Hello Fadi, I followed your advice and „burned“ the ISO under Jessie. Same result: In OF, there is no disk listed tu a USB string. There is also no „ud“ listed on devalias. OF doesn’t see the USB key, but the LED on the key is on. Maybe, it’s a OF issue. Anyway, I will burn a mini.iso under Jessie again to be DFSG compliant. I also got on booting a „Failed to start Kernel modules“ message. Best regards Carlos
