[SOLVED] Set up ZTE mf627 GSM Modem - almost there...

Hi eve!
I have this goddamn dongle that never worked...
I read alot of posts about it, tried installing usb_modeswitch and everything, but the device never showed up on NM.
Plus i saw a big change in the last year and logs show a very strange situation that it's not yet documented on any forum. In fact, i still can't understand how the hardware is abstracted now that HAL is deprecated... Kernel magic powder? Keel anyway, HAL was a bit junky ;-)

So when i stick it in, it first tell me

Apr 27 00:03:24 myhost kernel: usb 1-4: new high speed USB device using ehci_hcd and address 4
Apr 27 00:03:24 myhost kernel: scsi8 : usb-storage 1-4:1.0
Apr 27 00:03:29 myhost kernel: scsi 8:0:0:0: CD-ROM            ZTE      USB SCSI CD-ROM  2.31 PQ: 0 ANSI: 2
Apr 27 00:03:29 myhost kernel: sr1: scsi-1 drive
Apr 27 00:03:29 myhost kernel: sr 8:0:0:0: Attached scsi CD-ROM sr1
Apr 27 00:03:29 myhost kernel: sr 8:0:0:0: Attached scsi generic sg2 type 5
Apr 27 00:03:35 myhost kernel: usb 1-4: USB disconnect, address 4

!! Then! The device automatically shut down and restart givin theese new messages:

Apr 27 00:03:40 myhost kernel: usb 1-4: new high speed USB device using ehci_hcd and address 5
Apr 27 00:03:40 myhost kernel: option 1-4:1.0: GSM modem (1-port) converter detected
Apr 27 00:03:40 myhost kernel: usb 1-4: GSM modem (1-port) converter now attached to ttyUSB0
Apr 27 00:03:40 myhost kernel: scsi9 : usb-storage 1-4:1.1
Apr 27 00:03:40 myhost kernel: option 1-4:1.2: GSM modem (1-port) converter detected
Apr 27 00:03:40 myhost kernel: usb 1-4: GSM modem (1-port) converter now attached to ttyUSB1
Apr 27 00:03:45 myhost kernel: scsi 9:0:0:0: Direct-Access     ZTE      MMC Storage      2.31 PQ: 0 ANSI: 2
Apr 27 00:03:45 myhost kernel: sd 9:0:0:0: Attached scsi generic sg2 type 0
Apr 27 00:03:45 myhost kernel: sd 9:0:0:0: [sdb] Attached SCSI removable disk

At this point one may think that HAL now see a new modem and dbusses NM to create a new connection through the frendly wizard... but it doesn't...
Plus i get a ZTE MMC Storage on my "Computer" that i can't "safely remove"

Error detaching: helper exited with exit code 1: Detaching device /dev/sdb
USB device: /sys/devices/pci0000:00/0000:00:1a.7/usb1/1-3)
SYNCHRONIZE CACHE: FAILED: No such file or directory
(Continuing despite SYNCHRONIZE CACHE failure.)
STOP UNIT: FAILED: No such file or directory

So i tried usb_modeswitch with the setting i saw on http://ubuntuforums.org/showthread.php?t=1017630&page=3 and it just worsened the situation since it would only mound as an MMC once restarted.
HAL infos, gathered from the link above, made no difference...

lsusb give "Bus 001 Device 009: ID 19d2:0064 ONDA Communication S.p.A. ZTE MF627 AU" with various Interface descriptor ("bInterfaceClass 8 Mass Storage" and various "bInterfaceClass 255 Vendor Specific Class" , no modem though...)

Damn, i'm afraid that these dongles only work fine if you are a teenager with an unsure personality that needs to check her facebook profile every 5 minutes on a windlords svista...

did you install modemmanager? or as an alternative, you can try wvdial (using wvdialconf) to auto-detect and setup basic configuration file for it.

F*#ç s>*t!!! You mean modemmanager is the opt depend for NM to bring up the modem?!!!
...

sorry... thought it was wvdial...

So cool! This gives ZTE mf627 full linux support out of the box ;-)
And even the MMC reader seems to work! WoW

Love you all guys!

Cheers
