Spurious Detach Events with Phidget

Postby user123 » Thu Sep 24, 2020 2:10 am

Hi together,
I have a system of multiple Phidgets (1047-Phidget, HUB0000, DAQ1300, two OUT1100, ENC1000, STC1003). The HUB000 is connected to a Nanopi4 via custom-made usb-cable. this usb-cable has a 5V input cable so it wont get its power from Nanopi-USB-port. The grounds of Nanopi-USB-port, Powersupply and Hub are connected. I had the system running with a regular USB-cable but there where this detach events. i also had an external powered hub port tested. the thought behind the custom made cable was to prevent breakdown of the usb-port-power of the NanoPiNeo4 in case HUB000 pulls to much power. it has two ferrit cores on it. the detach Events are still there. It is very important for me to get rid of this events.
So i get this detach Events sometimes when i want to drive the motors and sometimes when i am doing nothing with the system. It is very difficult to say when they occur. i have the newest phidget library installed.
my logfile is attached. with the command dmesg in linux i found this:

USB disconnect, device number 2

Hi,

Your HUB0000 is running a quite old firmware v119. Please upgrade to the latest v127 using the Phidget control panel on a Windows or macOS machine and report back. There have been numerous USB bugfixes.
