USB bridge adapters are notoriously buggy. Your model may produce the
expected results with the drive you have attached. But can you guarantee
that it won't corrupt data for somebody else? There are definitely USB
bridges out there that will happily trim areas outside of the requested
block ranges.
Consequently, we have to err on the side of caution. If a device is not
reporting that a given feature is enabled, we defer the decision to the
user.
