I'm running into a weird issue with the latest updated Proxmox install where a USB 3 SSD (Samsung T5) passed through to a VM will not be recognized on the VM itself. The guest OS is Arch Linux, and this is what I get on the dmesg:

Code:
[    3.125565] usbcore: registered new interface driver usb-storage
[    3.150918] usb 3-1: Not enough host controller resources for new device state.
[    3.151180] xhci_hcd 0000:02:1b.0: xHCI xhci_drop_endpoint called with disabled ep (____ptrval____)
[    3.151188] xhci_hcd 0000:02:1b.0: xHCI xhci_drop_endpoint called with disabled ep (____ptrval____)
[    3.151194] xhci_hcd 0000:02:1b.0: xHCI xhci_drop_endpoint called with disabled ep (____ptrval____)
[    3.151238] xhci_hcd 0000:02:1b.0: Trying to add endpoint 0x81 without dropping it.
[    3.151249] usb 3-1: Not enough bandwidth for altsetting 0
[    3.168945] uas 3-1:1.0: probe with driver uas failed with error -12
[    3.169014] usbcore: registered new interface driver uas

For some weird reason, editing the machine type and downgrading it to i440fx-5.1 or so allows me to enable the USB 3 checkbox when passing the drive through, which "fixes" it, although I think I remember seeing a dmesg entry about the drive running in reduced performance mode.

Was wondering if anybody else was running into this issue?
 
I'm having this exact same issue, running on arm64. Have you found a fix?
Unfortunately not. My machine is a HP T620 thin client of all things, x86_64 arch.

For a temporary workaround I've formatted the drive as a LVM-thin and moved over my VM onto it, then expanded the size. Would be great if I could mount it within a VM, though.
