So what you're saying is, all BR players MUST have a USB port?
While a player could be designed to provide enough internal memory to avoid the need for a USB port if the manufacturer should happen to want to do it that way, such a player certainly wouldn't be competitive in the current marketplace.
I have browsed the manuals of some of the current players that do. They make no mention of the USB port being used for storage, i.e. with a USB thumb drive. All they talk about is connecting USB devices, like a keyboard. So how can I tell if any given player which has a USB port, can use it for actual storage?
Can you provide a link to a manual which doesn't mention USB storage?
Support for non-storage devices (like keyboards) is a relatively recent development, so I'd expect companies to make a point of mentioning that feature in competition with players that don't provide that support.
As I said, THX 1138 requires the presence of an external USB storage device. It won't play without one. So you can see the problem.
Just because a manual doesn't mention it, doesn't mean USB storage isn't supported. As you can see in the various "profile" requirements described in the Wikipedia article, any BD player which supports either "BD Live" or 3D, must also support at least 1GB of storage. I doubt that Sony would allow companies to violate that licensing requirement. As an apparent cost-conainment measure, some current players actually provide no internal storage of their own, thus requiring users to purchase a USB flash drive to provide it if they want to use those features, but that storage is still "supported".
