QEMU offers two attributes for handling reset requests of an USB host device: guest-reset and guest-resets-all. When combined they act as follows: 1) guest-reset=false The guest is not allowed to reset the physical USB device. 2) guest-reset=true,guest-resets-all=false The guest is allowed to reset the device when it is not yet initialized (aka no USB bus address assigned). Usually this results in one guest reset being allowed. This is the default behavior. 3) guest-reset=true,guest-resets-all=true The guest is allowed to reset the device as it pleases. Now, there's a clear 1:1 mapping with our representation of guestReset, so generating cmd line is trivial.
