Hi,
I’m using the ATRM50 usb port to connect to an industrial device. The device uses a FT232 USB-to-serial converter. Since the converter is built into the device, I cannot use a different USB-to-serial converter.
The industrial device connects perfectly fine to my Raspberry PI and my windows machine.
Other USB-to-serial converters work fine on the ATRM50.
On the ATRM50, the connection usually fails with the following kernel messages:
[ 999.926620] usb usb1-port2: disabled by hub (EMI?), re-enabling…

[ 1035.372242] usb usb1-port2: attempt power cycle

I have tried different USB cables without success.
Anyone else experiencing similar issues? Any ideas?
best regards
