@lightsout: checked it immediately and unfortunately you're right... Update this weekend. (I *DID* process the new driver, but just forgot somehow to copy the new driver files... ) @Nakatomi2010: I DO know that. Check DP MassStorage's changelog for an explanation That HWID is assigned to the ati3112r driver. That was the same driver that was used before V6.02 of DP MassStorage for ALL Si3112r devices, but is now only kept for compatibility reasons (for ATI chipset based motherboards). But I've already built in a work-around, I don't understand why it doesn't work... EDIT: setup worked fine UNTIL the reboot where setup really starts? (The reboot after the file copying process?)
