And the drive would be open source later time.</div><div> You add the device L850 of Fibocom in the ModemManager early time, and now the Fibocom want to add the L860 by itself, and I work for Fibocom.

<br>
Is this PCIe library a new one that you're writing?<br>
What device is this?<br>
<br>
Cheers!<br>
