A K3765-Z mobile broadband pen is working fine on other laptops/other distros (including Ubuntu 13.10), but is not being recognized on a cold boot on my new Clevo P150SM (which only has USB3 slots - the ones with a blue insert).

$ uname -a

Linux khaki 3.11.0-17-generic #31~precise1-Ubuntu SMP Tue Feb 4 21:25:43 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

On a cold boot, /var/log/syslog shows:

But nothing more happens. There are no /dev/ttyUSB devices setup, and network manager does not detect the pen.

If I use the pen under Windows, and do a hot-reboot to Ubuntu, it gets to the point where the network manager detects the pen (but I have still been unable to successfully establish a connection using the same parameters that I used on other laptops).

/var/log/syslog following a hot reboot shows:

Any ideas on how to get the pen working ? (Without booting into windows 1st :-)

Update:
Regarding the suggestion of adding file /etc/udev/rules.d/90-zte.rules with:

SUBSYSTEM=="block",SUBSYSTEM=="scsi",ATTRS{model}=="USB Storage FFE9",ACTION=="add",RUN+="/sbin/modprobe usbserial vendor=0x19d2 product=0x2000"

and then performing (after pen insertion)

# modprobe usbserial vendor=0x19d2 product=0x2000

Once I get the time to investigate, I will post more details.
