Huh? Userspace implementations /can/ be code-reviewed (but they can't
crash your machine), they /can/ be and are shipped everywhere, they /do/
auto-load when the device is inserted. And if there should be an issue
with power management (is there any?), then improve the ABI and libusb
can surely be improved. I don't see why a device with a userspace
driver cannot be included in power management.
