Hi,

Figured you folks would know.

Have a bag full of USB cables.
Some are probably the older USB 1, and some the newer 2.0.

No labels on them.

Is there any distinguishing marks on the cable or connectors that I'm
missing perhaps that tells one which is which ?

Thanks,
Bob

I thought he 2.0 protocol is for the electrons. I think old cables still
work. I could be wrong.

I use them interchangably, and notice no difference at all.
