Mit dem Devlink komm ich mit allen 3 Beispielen nicht klar. Die Sache mit dem FileIO hört sich einfacher an, werde die Steuerung gleich ebend wieder anschließen und schauen, ob es machbar ist.
In der sysconf.br bin ich, wie bestimme ich den Pfad? Bzw. wie sollte er heißen?
Wäre der Pfad so richtig
/DEVICE=IF4.ST1
Habe es mit folgenden Beispiel aus der Hilfe versucht: Beispiel 1
AsUSB - Beispiel 1 in ANSI C
Beispielbeschreibung

Der haut mir den Compiler entsprechend so um die Ohren. Im Einsatz ist ein Sandisk Cruzer. (nicht von B+R bezogen). Das Mapping hab ich auf IF.ST1 gelegt, wo der USB Stick steckt.
