Hello,
bear with me - this is nearly a short (?) story ... but i have the following problem:
I have a powered ush-hub.
Connected to the hub are
a Astrometa USB Tv stick and
a 2.5” harddisk.
This hub is connected to a USB-switch, by which the connection is directed either to a Raspberry Pi 3b+ (running Linux raspberrypi 4.19.66-v7+ #1253 SMP Thu Aug 15 11:49:46 BST 2019 armv7l GNU/Linux) or
Raspberry Pi 4b (running Linux raspberrypi 4.19.75-v7l+ #1270 SMP Tue Sep 24 18:51:41 BST 2019 armv7l GNU/Linux)
Power adapter is the original Pi 5.1V 3A
Cable length is about 20 cm.
Switching to the Rpi 3b+ the hub is recognized and the correct devices are installed.
Switching to the Rpi 4 the hub is never connected (I tried USB3.0 and USB 2.0)
Switching the cables doesn’t help nor does switching the ports on the USB switch.
Raspberry Pi 3 always works – Raspberry 4 never. So any hardware problems (except for Raspi 4) can be excluded.
Output (short dmesg) when switching to Raspi 4
