Using USB Port on VM Like Normal Computer?

Hi!
I’m new to Proxmox. I’ve tried to add “USB Device ID” as well as “USB Port” to the VM from Web GUI. But the VM only detect flashdisks that had been added in the Proxmox.

Expected result, naturally:
(From VM)
Insert flashdisk A —> VM detect flashdisk A
—> Eject flashdisk A
—> Insert flashdisk B —> VM detect flashdisk B,
all without having to restart the VM. Just like normal computer.

Is there a workarround to achieve this? Or anything close?

Sorry for the noob question.

Proxmox 8.02, Kernel 6.2

Code: 
lsusb -t

/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/10p, 20000M/x2
    |__ Port 10: Dev 2, If 0, Class=Hub, Driver=hub/4p, 5000M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/16p, 480M
    |__ Port 5: Dev 2, If 1, Class=Human Interface Device, Driver=usbhid, 12M
    |__ Port 5: Dev 2, If 0, Class=Human Interface Device, Driver=usbhid, 12M
    |__ Port 6: Dev 3, If 0, Class=Human Interface Device, Driver=usbhid, 1.5M
    |__ Port 6: Dev 3, If 1, Class=Human Interface Device, Driver=usbhid, 1.5M
    |__ Port 9: Dev 4, If 0, Class=Human Interface Device, Driver=usbhid, 12M
    |__ Port 10: Dev 5, If 0, Class=Hub, Driver=hub/4p, 480M
    |__ Port 11: Dev 6, If 0, Class=Hub, Driver=hub/4p, 480M
    |__ Port 14: Dev 7, If 0, Class=Wireless, Driver=btusb, 12M
    |__ Port 14: Dev 7, If 1, Class=Wireless, Driver=btusb, 12M
 
if you passthrough Flashdisk A to your VM ones then the VM will always detect flashdrive A if it is inserted. Same goes for flashdrive B, etc. No reboot is required

But if you passthrough flashdisk A for the first time, you have to reboot the VM?
Also, if you remove flashdisk A from passthrough, and then in the future add it again, we still need to reboot the VM, don't we?
 
To solve problem in general, I can recommend PCIe passthrough of a controller directly to the VM. Afterwards, everything that is plugged in will automatically be detected in the VM.

I've tried it and did not have to reboot at all.

Would you please point out which one?
