I have the latest version of Volumio on a Raspberri Pi 4. Power supply can deliver up to 5 A, it is the sigma 11:

Connected a NVMe to USB ICY BOX 2 TB drive that contains my music.
When I copy files to the drive through the SMB share, the connection to the USB drive is lost due to the limited power from the USB port. I solved this by adding a powered USB hub from UGreen, which should work with the pi without issues.
But it doesn’t. I need to disconnect and reconnect the USB drive physically before the music on it can be accessed.
I have been playing with commands like:

echo ‘1-1’ | sudo tee /sys/bus/usb/drivers/usb/unbind
echo ‘1-1’ | sudo tee /sys/bus/usb/drivers/usb/bind
and uhubctl:
I can switch off and on the power on the USB port that has the USB drive connected to it. I see that because the power led on the ICY BOX switches off and on again. But the OS doesn’t see the drive:
/mnt/USB or /media/Music stays empty.
All without any success.
lsblk -fp never shows the USB drive unless it is disconnected and reconnected physically.
