Hi,
sorry for spaming the mailinglist. Out of desperation I just tried one more
experiment. If I attach the "powered usb hub" directly to the BeagleBone
and connect my "custom made usb hub" on the "powered usb hub", I receive
the following messages:
[ 49.784746] usb 1-1.1: device not accepting address 11, error -71
[ 50.794745] usb 1-1.1: device not accepting address 14, error -71
...
[ 55.144832] hub 1-1.1:1.0: hub_port_status failed (err = -71)
[ 55.151082] hub 1-1.1:1.0: hub_port_status failed (err = -71)
...
[ 55.399949] hub 1-1.1:1.0: activate --> -19
Any clue?
Thanks for any answer.
Best regards,
Stefan
