Good afternoon,
I'm sending this message here, because the problem is happening only on my
Debian machine.
I'm developing applications for Ingenico POS devices EFT 930S and ICT 220.
They run Telium platform and I use an Windows application to load the files
into the devices.
The vendor provide a Windows Local Loading Tool (LLT) that connects
through their "serial" interface. Actually, it is a USB interface that
works as a serial port.
The tool establishes a PPP link and after that there is a FTP connection.
My environment is a Debian Jessie running *Kernel 3.16.0-4-amd64 #1 SMP
Debian 3.16.7-ckt2-1 (2014-12-08) x86_64 GNU/Linux.*
This Debian is a VirtualBox host for a Windows XP SP3 (32 bits) guest
machine that runs the LLT to connect to the terminals.
The version of the VirtualBox is:
*virtualbox-4.3 4.3.20-96996~Debian~w
amd64 Oracle VM VirtualBox*
It was downloaded from the Oracle Repository.
Some time ago, when I was using a different version of the kernel (I'm not
sure which one right now) everything was working fine. After the update the
things got messy.
I have 2 problems. If the ModemManager daemon is running, it restarts the
device few seconds after it's connected to the machine's USB port. So I
stopped the ModemManager. (problem solved)
The second problem is that the PPP connection is never established.
I activate the USB device on the VirtualBox, the Windows XP detects it, the
LLT recognize that there is a COM port active, but the PPP link is not
established. There is this error RAS 777 that the documentation explain as:
*Terminal is not responding. Check connection (check the serial cable or
USB cable is correctly plugged) and check that terminal is waiting for a
connection. If not check Selecting communication port or Installing the
null modem driver.*
I made all the checks and everything is ok but it keeps returning this
error.
It's valid to point that I use the same VM (in this Debian host) to
connect to other vendors' POS using their own software and my Debian
connects via Minicom to then to get serial output.
Then I exported my VM and used it on a Ubuntu machine, disabled the
ModemManager and everything worked pretty well. (cables and POS devices are
the same)
*The Ubuntu distro is 14.04 and the Kernel 3.13.0-43-generic #72-Ubuntu
SMP.*
I did some tests in the Debian machine with the udev and the Linux is
recognizing the USB device.
I got this in the /var/log/messages when I plugged the device.

And with this udev rule:
*KERNEL=="ttyACM*", SUBSYSTEM=="tty", ATTRS{idVendor}=="079b",
ATTRS{idProduct}=="0028", MODE="0666", SYMLINK+="telium%n"*
I got the link telium0 in the /dev folder.
But when I activate the device in the VirtualBox, so my VM could see it,
the link disappears but the VM detects the device.
What else could I send to you, so you could help me to solve this problem?
Thanks in advance.
Kind Regards
