Revision code on STUSB4500

[danielweberdlc]

We have a batch of chips labelled M27400 and another marked M37400.  Does this marking indicate the version number of the chips?  I'm seeing a difference in behavior between them (the M34700 are reporting PE states I haven't seen previously).

 

Thanks,

Please include legible photos of the markings so that they can be analysed in more detail.
