Hi, All

Now, I'm intergrating HUAWEI 3G Modem E261 to my system. customer board is based on SabreAuto 6Q, android 4.3.

After insert modem, uart log is as below:

usb 1-1: new high speed USB device number 5 using fsl-ehci

usb 1-1: device v12d1 p1446 is not supported

scsi3 : usb-storage 1-1:1.0

scsi4 : usb-storage 1-1:1.1

scsi 3:0:0:0: CD-ROM HUAWEI Mass Storage 2.31 PQ: 0 ANSI: 2

scsi 4:0:0:0: Direct-Access HUAWEI SD Storage 2.31 PQ: 0 ANSI: 2

sd 4:0:0:0: [sda] Attached SCSI removable disk

sda: detected capacity change from 4005527552 to 0

===========

and /sys/bus/usb/devices information is as below:

root@sabreauto_6q:/sys/bus/usb/devices # ls

1-0:1.0

1-1

1-1:1.0

1-1:1.1

2-0:1.0

usb1

usb2

==============

there is nothing in /proc/bus:

root@sabreauto_6q:/proc/bus # ls

input

pci

usb

root@sabreauto_6q:/proc/bus # cd usb

root@sabreauto_6q:/proc/bus/usb # ls

I don't know why it recognized as Mass storage device, could someone help me? many many thx..

Hi jianhua, message

"device v12d1 p1446 is not supported"

means that there is no driver for it (or it is incompatible, from other kernel).

You should find correct driver for this device.

Also many 3G modems has second "Mass Storage"

capability, as you see. Actually this subject is well described on web.

Connect ANY 3G dongle to ANY android tablet... - xda-developers

Success with USB 3G modems on Android | freedune

2.2 froyo - How to install not-supporting-out-of-the-box 3G modems on Android 2.2 - Android Enthusiasts Stack Exchange

Additionally please be aware of huge power consumption of 3G modems (up to 2.5A peak),

probably you will have to use separate power supply for it.

Best regards

Hi Chip

thx for your reply. I've read the website you provided.

I think it is because of USB-OTG port.

I change to a common USB port ( I use HUAWEI-EM770W now, not use E261), the modem can be recognized. but it still cannot connect to internet (gprs) function.

following is logcat -b radio:

Hi jianhua,

suggest to check sim and network settings

in modem.

Best regards
