10gb JBOD enclosure but only 5gb in VM ?

[rofo69]

I have a Yottamaster fs5c3 which is a USB 3.1 gen 2 jbod enclosure that reports correctly when using lsusb -t in the proxmox host:-

/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/10p, 10000M
|__ Port 2: Dev 2, If 0, Class=Hub, Driver=hub/4p, 10000M
|__ Port 2: Dev 7, If 0, Class=Mass Storage, Driver=uas, 10000M
|__ Port 3: Dev 3, If 0, Class=Hub, Driver=hub/4p, 10000M
|__ Port 1: Dev 4, If 0, Class=Mass Storage, Driver=usbfs, 10000M
|__ Port 2: Dev 5, If 0, Class=Mass Storage, Driver=usbfs, 10000M

I've passed 2 disks through to a VM using the 'use USB port' option in the hardware settings and in the VM I'm only seeing 5000M speed with the same lsusb -t command:-

: Bus 003.Port 001: Dev 001, Class=root_hub, Driver=xhci_hcd/15p, 5000M
|__ Port 001: Dev 002, If 0, Class=Mass Storage, Driver=uas, 5000M
|__ Port 002: Dev 003, If 0, Class=Mass Storage, Driver=uas, 5000M

Also, when using the qm monitor prompt for this VM I get this:-

qm> info usbhost
Bus 2, Addr 5, Port 2.3.2, Speed 5000+ Mb/s
Class 00: USB device 2109:0715, VLI Product String
Bus 2, Addr 4, Port 2.3.1, Speed 5000+ Mb/s
Class 00: USB device 2109:0715, VLI Product String
Bus 2, Addr 7, Port 2.2, Speed 5000+ Mb/s
Class 00: USB device 2109:0715, VLI Product String


Any ideas on whats going on ?
