Hi all,
I'm sure this patch will prevent the assertion failure due to the
inconsistent ep and pid (UBS_TOKEN_SETUP) (
https://lists.gnu.org/archive/html/qemu-devel/2021-06/msg07179.html).
For UHCI (https://gitlab.com/qemu-project/qemu/-/issues/119) and OHCI (
https://gitlab.com/qemu-project/qemu/
Sometimes, `ep` is not enforced to 0 when `pid` is `USB_TOKEN_SETUP`. I
trigger this through dwc2
(https://lists.gnu.org/archive/html/qemu-devel/2021-06/msg07179.html).
