Cannot remember seeing it, but that doesn't count much these days... I don't think it can be a Gobi device. I haven't seen the lsusb output or equvialent, but assuming that there is a 1-1 mapping between USB interfaces and ttyUSBx devices, then ttyUSB0 would not be an AT capable port if this was a Gobi device. But I do see "Revision:MDM6085-11" in the log, and the MDM6085 chipset is definitely a 3G EVDO Gobi chipset. This doesn't necessarily mean that ZTE has licensed Gobi firmware for it, but it could mean that one of the unknown serial ports is actually a QMI/net port. We need probing or Windows *.inf files to tell more.
