MSC: Is it possible to allow deletes but not creating new files or modifications?

[trullock]

I have a data logging device, which exposes its logs via a USB MSC device. I want users to be able to delete old logs via MSC, but not to use the device as a real MSC by adding files or modifying files.

Is this simple to achieve (and how)?

Or not worth it?

I'm an experienced coder but have no experience with SCSI commands or how USB MSC really works
