Hallo zusammen,
ich habe folgendes Problem.
Ich habe ein Programm geschrieben, welches auf einen RS485 Converter(USB) zugreift. Dieses Programm fragt im bestimmten Zyklus diverse Sensoren ab. Dies funktioniert auch über Tage und Wochen einwandfrei.
Nun kam jedoch auch ein UMTS-Stick hinzu. Leider bekomme ich jetzt die Problematik, dass irgendwann zwischen Tür und Angel sich die Zuordnungen der dev ändern.
Nach dem Boot habe ich folgendes:
/dev/ttyUSB0 > RS485
/dev/ttyUSB1 > UMTS
/dev/ttyUSB2 > UMTS (Vermutlich SD Reader)
Den Modeswitch habe ich bereits drin und das funktioniert soweit auch ganz gut...vermutlich *g*
Nun habe ich jedoch den Fall, dass RS485 aus einmal auf ttyUSB3 liegt:

Beim lesen ist mir dann das "overcurrent" aufgefallen. Hierbei handelt es sich um einen Raspberry PI.
Kann es sein, dass nach einer gewissen Zeit (wieso auch immer es vorher einen Tag läuft) der Strom auf dem internen USB-HUB zu groß wird und er dann den RS485 Converter raus kickt um ihn dann wieder neu zu initialisieren oder habe ich hier ein anderes Problem?
Würde mich über Tipps freuen.

PS: Das mit dem symlink und der festen Zuordnung der Hardware wäre jedoch trotzdem interessant :-)

Beim lesen ist mir dann das "overcurrent" aufgefallen. Hierbei handelt es sich um einen Raspberry PI.
Kann es sein, dass nach einer gewissen Zeit (wieso auch immer es vorher einen Tag läuft) der Strom auf dem internen USB-HUB zu groß wird und er dann den RS485 Converter raus kickt um ihn dann wieder neu zu initialisieren oder habe ich hier ein anderes Problem?
Würde mich über Tipps freuen.

PS: Das mit dem symlink und der festen Zuordnung der Hardware wäre jedoch trotzdem interessant :-)
