Hi,

 

I have two 3G modem (HUAWEI E160E and ZTE K3565). When I connect HUAWEI 3G modem on the i.MX53QSB with ANDROID, the dongle is correctly mounted by Linux :

 

usb 1-1.2: new high speed USB device using fsl-ehci and address 11

usb 1-1.2: New USB device found, idVendor=12d1, idProduct=1003

usb 1-1.2: New USB device strings: Mfr=2, Product=1, SerialNumber=0

usb 1-1.2: Product: HUAWEI Mobile

usb 1-1.2: Manufacturer: HUAWEI Technology

option 1-1.2:1.0: GSM modem (1-port) converter detected

usb 1-1.2: GSM modem (1-port) converter now attached to ttyUSB0

option 1-1.2:1.1: GSM modem (1-port) converter detected

usb 1-1.2: GSM modem (1-port) converter now attached to ttyUSB1

scsi9 : usb-storage 1-1.2:1.2

scsi10 : usb-storage 1-1.2:1.3

scsi 9:0:0:0: CD-ROM            HUAWEI   Mass Storage     2.31 PQ: 0 ANSI: 2

scsi 10:0:0:0: Direct-Access     HUAWEI   MMC Storage      2.31 PQ: 0 ANSI: 2

sd 10:0:0:0: [sda] Attached SCSI removable disk

 

ANDROID discovers with "telephony registry" the operator, and creates a PPP connection. And then I can access to the web with a 3G connection.


With the ZTE 3G modem, it doesn't work. When I connect the modem to i.MX53QSB, it is partially discovered :

 

 

usb 1-1.2: new high speed USB device using fsl-ehci and address 13

usb 1-1.2: New USB device found, idVendor=19d2, idProduct=2000

usb 1-1.2: New USB device strings: Mfr=2, Product=1, SerialNumber=0

usb 1-1.2: Product: ZTE CDMA Technologies MSM

usb 1-1.2: Manufacturer: ZTE, Incorporated

scsi11 : usb-storage 1-1.2:1.0

scsi 11:0:0:0: CD-ROM            ZTE      USB SCSI CD-ROM  2.31 PQ: 0 ANSI: 0

 

ANDROID doesn't discover the operator and doesn't create a PPP connection.

 

Any idea?
