Did I kill my MC7455?

Picked up a used 'Outdoorrouter' (EZR30) with an EM7455 installed and working with my T-Mobile SIM.

As I couldn't find any way to send AT-commands to the modem thru the (OpenWRT-based) OutdoorRooter web UI, I placed it into a USB adapter to connect it my Windows PC to update firmware and other 'magic', but it only appeared as a USB storage device - no COM ports. Now my Rooter'd RBM33g doesn't see it at all and back in the EZR30, it no longer works either. :-(

Turns out my adapter was not correct for a USB modem (one of these: https://amzn.to/3H80g8E ) It's intended for mSATA storage card only, (no SIM slot should have clued me in, but i figured I didn't need the SIM for what i wanted to do...)

I can't tell if this improper connection has killed/damaged it, or maybe it can be recovered somehow for use via USB (for eventual Rooter install on the EZR30).

Any tips appreciated! Paul.

Might just try to use one of these and see if it shows up on your windows device manager:

I gave up on the OutDoorRouter EZR30 (mostly since it only had a 100mb ethernet...) But I have re-purposed the nice outdoor case and bulkhead N-female to SMA antenna connections. I pulled the board and replaced it with a Mikrotik RB11G running ROOter. so now it's an 'OutDoorROOter' https://flic.kr/p/2n4MU9r :-)
