Some other update:
i tested it on a laptop device with linux installed. there it works without detach problems. therefore the problem is somehow connected to the raspberry pi. i have set the raspberry usb output from 600mA to 1.2A. even though there is a usb-power-hub still in between raspberry and 1047 board so there should not be that much power consumption. still the problem sometimes occurs.
(raspi is powered with 2.5A and 5.1V like recommended)
btw. i also changed the usb-power-hub and the power supply of raspi to be sure that it's not the problem.

Next update: i installed the phidget22 library on a ASUS tinkerboard. here the setup runs without the detachment problems. is it possible that the 1047-board is not raspberry pi compatible?

Another test on a Raspberry Pi 4 was successful. Also on a Nanopi Neo4 its working. the problem seems to be the Raspberry 3B+ USB.

Some of the Raspberry Pi boards have USB issues, and have for a long time.
