Hello.

Recently got a new USB dongle - Huawei e392. Initially it worked fine, had no problems, but then suddenly it stopped connecting. I tried everything, forcing 3g, forcing 4g, re-upgrading firmware and uploading a .bin file, nothing works.

It just tries to connect, gets disconnected, and unplugs the USB modem, then does it over and over again.

Here's the log.
