Read-Only Powered USB Hub

post #1 of 6
Thread Starter 
Does such a hub exist? Any number of ports would be sufficient as I only need one.
post #2 of 6
I doubt it; one port wouldn't really be a hub and in any case the write control isn't handled by the port. You can disable write on a specific USB drive or on all USB ports pretty easily; what is it exactly you are trying to accomplish?

I'm planning on getting a spectro. meter sometime soon or in the future and I'd like to offer to calibrate displays but, I'm concerned with the USB virus that popped up a while back. I'd like to connect it to PCs read-only instead of dragging a laptop along. I guess I'm being a tad paranoid about it but, I don't really want to chance messing up an expensive meter.


Thanks for the response, sorry if I'm being stupid about this tongue.gif.

I don't see how a virus could do anything to a USB device like a spectrum analyzer? The USB viruses just copy a file to a flash drive and make it autoexecutable.

Data diode is what you want. Unfortunately I can't find anything commercially available, but they do exist.

Looks like I'll be shelving the read-only idea if that's the case. Thanks for all the responses smile.gif.
