Hi Kristen,
I'm sorry for my late reply. I understood the issue which you are encountered. When the _STA is not defined, acpi assumes that the device is always there. But actually, the device is not connected. So, when the device is added, acpi_device structure has already exist. Is my understanding right?
I've tried to solve this issue. But I could not find better solution, unfortunately. So I think your idea is good now,
