Did you ever get this fixed?  I have the same issue.

Likely the switch cannot provide sufficient power on the port to power both the phone and the expansion module. What power rating does the switch have?

I figured it out.  In the 3PCC GUI, the USB was turned off.  It's got a
weird set up.  It says Disable USB and that's Yes by default, so you
have to change it to no.  Thanks!
