Multi USB Device Pass Through Hardware not found

[Krie9er]

Hi, I am really new in the universe of Proxmox.

I want to pass to a windows 10 14 USB-Drives.

To reach this: I increased the Max_USB_Devices variable to 25 (because more to come)
Then I updated the vm config and added all usb-storages via bus-port and as usb3. After a reboot of the proxmox server I am now able to pass the devices to the vm, but it can not been "read" by the windows. I see in the device manager just "unknown USB device(invalid configuration descriptor)".

As a alternative I tried one alternative way: I added the usb controller as a pci device for the VM. But this made Proxmox crashing as soon as the Vm starts :-/

I used so far the proxmox docu: https://pve.proxmox.com/wiki/USB_Devices_in_Virtual_Machines#More_Devices
but was not really successful :-(

This is my lsusb -t. I want to add all devices on bus 4

I would be really happy if you can help me or give me a hint.
I could manage to add 5 USB devices but the rest will not be "accepted" and I really question, why xD

Kind regards
