Title:
  usb-net on aarch64 has wrong class IDs, isn't recognized by Windows

Status in QEMU:
  Expired

Bug description:
  If I run qemu-system-aarch64 with "-device usb-net,...", the resulting
  USB device will be seen in the guest as class 0x2, subclass 0x2,
  protocol 0xFF, instead of the expected class 0xe0, subclass 0x1,
  protocol 0x3. This prevents Windows' in-box class driver from binding
  to the device. On x86 and x64 Windows, this is not an issue, as
  another driver will bind to the device, but in Windows for ARM64, that
  driver is unavailable, so the USB device is incorrectly recognized as
  a serial port.

  Installing a modified version of the inbox driver in "Disable Driver
  Signature Enforcement" mode solves the issue, but it's not a very
  clean solution.
