"No drivers found" GoClever tab T76 and Huawei E3131

Post by UnKaiF » Fri Jan 09, 2015 10:58 pm

Hi, Josh !

Android 4.0.4 & 3.0.8 kernel onboard.
In config.gz i'm found that the needed modules is already built-in my kernel.

Code: Select all

CONFIG_PPP_ASYNC=y
........
CONFIG_USB_SERIAL_WWAN=y
CONFIG_USB_SERIAL_OPTION=y
........
CONFIG_USB_ACM=y
But something in my system switching donge modes: (From Zero-CD to RNDIS mode.)

Code: Select all

<6>[  152.036660] usb 1-1: new high speed USB device number 2 using dwc_otg
<3>[  152.858310] usb 1-1: device v12d1 p1f01 is not supported
<6>[  152.906705] scsi0 : usb-storage 1-1:1.0
<6>[  153.116631] usb 1-1: USB disconnect, device number 2
....................
<6>[  158.336912] usb 1-1: new high speed USB device number 3 using dwc_otg
<3>[  159.108193] usb 1-1: device v12d1 p14db is not supported
<6>[  159.210151] cdc_ether 1-1:1.0: eth0: register 'cdc_ether' at usb-dwc_otg.0-1, CDC Ethernet Device, 58:2c:80:13:92:63
<3>[  159.301508] init: guoyq service_start name 'dhcpcd_eth0' 
<3>[  159.400420] init: guoyq service_start name 'dhcpcd_eth0' 
....................
<7>[  170.157090] eth0: no IPv6 routers present
<6>[  189.867877] usb 1-1: USB disconnect, device number 3
<6>[  189.873156] cdc_ether 1-1:1.0: eth0: unregister 'cdc_ether' usb-dwc_otg.0-1, CDC Ethernet Device
I'm looked at system folders about usb_modeswitch already installed, but found nothing.
Where to look ?

Second question: Sir, can you explain me why HiLink-like dongles don't work with android in RNDIS mode ? What kind of software (modules/services) nedded ? Where I can get info about it ?

Thank's alot,
UnKaiF.

I have a tablet with a tool named "usbdongle" which contains stolen code from usb_modeswitch. There may be variants.
If you can, open an adb shell on the device via USB from a PC. Type "usb" followed by <Tab>; if the shell is a recent version, you should get a list of possible commands starting with "usb..." ( the Linux way).

HiLink is a proprietary mode AFAIK. Huawei engineers have provided me with a 'switch' code intended for Android, so that every Huawei device I have encountered so far can be brought into plain PPP mode. This code is used in PPP Widget 1/2 of course.

You really will have to disable that other mode-switch tool for things to work properly ...

Ok. Check it tomorrow. (Something like "usbdongle" I think I've seen). Thanks :-)

I've temporary renamed
/system/bin/usbdongle -> ubdongle.bak
/system/bin/usbdongled -> ubdongled.bak,
then reboot device.
Nothing changed in dmesg log (except error - file usbdongled not found). :(

I've tried to switch modem to "modem only" mode with AT commands. Has three ttyUSBn in linux. Plugging modem into tablet - "device vXXX pXXX in not supported" again. May it be "vendor lock" somewhere in kernel ?

You have PPP Widget 2 installed and ready on the workspace, right?

If so, enable logging, plug the modem in and after a while check the "USB log"
