-Assert failure in `usb_ep_get` : Assertion `pid == USB_TOKEN_IN || pid == USB_TOKEN_OUT` failed.
-Description of problem:
-Assert failure in `usb_ep_get` : Assertion `pid == USB_TOKEN_IN || pid == USB_TOKEN_OUT` failed.
-
-The TD PID needs to be either `USB_TOKEN_IN` or `USB_TOKEN_OUT` in `usb_ep_get`, but in the caller `uhci_handle_td` it may be `USB_TOKEN_SETUP`. 
-
-An unprivileged guest user may be able to reach the assertion, I think this bug is quite akin to CVE-2024-3567 (https://gitlab.com/qemu-project/qemu/-/issues/2273) :
-
-Users are not directly able to craft URBs, however as a user, one might be able to find a kernel path that would send a TD with PID `USB_TOKEN_SETUP` to QEMU (which is called `USB_PID_SETUP` in Linux).
-For instance in the Linux Kernel,  `uhci_submit_control` in `drivers/usb/host/uhci-q.c:789`  does link a `USB_PID_SETUP` TD to the URB.
-Steps to reproduce:
-Minimized reproducer:
