GL-E750v2 Mudi no longer has /dev/cdc-wdm0

Hi, I recently bought a Mudi GL-E750V2, and trying to use with Visible.

I was able to connect, however the signal was unstable, often cutting out and reconnecting, and sometimes hanging on "Trying to connect." Switching back and forth from vzwinternet and internet would help for a little while, but eventually would disconnect completely. Tried different MTU's, TTLs, and still had this issue.

Searching on the forums, I found some instructions on how to make the connection more stable:

However, once I did this, /dev/cdc-wdm0 disappeared, and all I'm left with is /dev/ttyUSB0-3.

I've tried reinstalling the firmware. I've also tried UBoot. After doing so, cdc-wdm0 still remains missing. I'm at the point where I'm ready to give up on Visible, and instead order a T-Mobile tablet sim, but I would like to unbork this router. Is there anything else I can do, short of returning it?

Thanks in advance for any help!

I think you changed the protocol of the module

Let me debug it remotely?

When I go to share devices on goodcloud, there's no option for sharing to support. It asks for username/email/phone number. To whom should I share?

Edit. Figured it out. PM'd you the info. Thank you!
