[Bug 1875080] [NEW] USB host device data transfer with control endpoint

[Armin]

Public bug reported:

QEMU emulator version 4.2.0
Host -> Arch Linux kernel version: 5.4.34-1-lts
Guest -> Various Linux Distros

I sent a control message with data through endpoint zero.
On the other side message is received with all fields correct except data 
buffer.
I've tested the data field inside guest with usbmon and data field was correct 
but after packet leaved qemu, data filed is lost.

** Affects: qemu
     Importance: Undecided
         Status: New

** Summary changed:

- USB host device data transfer of control endpoint
+ USB host device data transfer with control endpoint
