Answer 1

I also have a HUAWEI k3765 and it's not working.
I'm a little confused about the way some of you solved it, and need some advice.
I tried to recompile modemmanager-0.3.2 against ppp-2.4.5-1 but doesn't work, in my system with kernel26 2.6.32.1-1 and networkmanager 0.7.2-1.
My dmesg shows this, when I connect the modem:
usb 3-3: new high speed USB device using ehci_hcd and address 6
usb 3-3: configuration #1 chosen from 1 choice
scsi3 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 6
usb-storage: waiting for device to settle before scanning
scsi 3:0:0:0: CD-ROM            Vodafone CD ROM (Huawei)  2.31 PQ: 0 ANSI: 2
sr1: scsi-1 drive
sr 3:0:0:0: Attached scsi CD-ROM sr1
sr 3:0:0:0: Attached scsi generic sg2 type 5
usb-storage: device scan complete
It seems not to being recognizing the modem and not creating ttyUSB0 and ttyUSB1.
So, it would be nice to know which versions you are using from programs listed below, with a working k3765:
-networkmanager
-modemmanager
-ppp
-kernel26
By the way... A HUAWEI E220 it's working normally in my system.
Thank's.
