peter at x240:~$ sudo mbimcli -d /dev/cdc-wdm1 --query-device-caps
[/dev/cdc-wdm1] Device capabilities retrieved:
          Device type: 'embedded'

peter at x240:~$ sudo mbimcli -d /dev/cdc-wdm1 --query-device-caps
error: operation failed: Transaction timed out

Again, the is difficult for me to reproduce as I can sometimes call it
several times in a row without timeout. This happens with mbimcli 1.6.0 (as
shipped with Ubuntu 14.04) as well as with mbimcli 1.13.0 which I just
built from the latest sources on the git repository.

Regards

Peter
