USB_ModeSwitch

Posted: **10 May 2012, 22:07**

Hi,

I just received four Hawei UMG1831 and have been trying to get them going, not succesful so far.
I've tried them with this config file:

Code: Select all

# ######################## 
# Huawei UMG1831 
# 
DefaultVendor= 0x12d1 
DefaultProduct= 0x1446 

TargetVendor= 0x12d1
TargetProduct= 0x1404 

HuaweiMode=1

But I still get only

Code: Select all

SCSI inquiry data (for identification)
-------------------------
  Vendor String: HUAWEI  
   Model String: Mass Storage    
Revision String: 2.31
-------------------------

USB description data (for identification)
-------------------------
Manufacturer: Huawei Technologies
     Product: HUAWEI Mobile
  Serial No.: not provided
-------------------------
Sending Huawei control message ...
Error: sending Huawei control message failed (error -32). Aborting.

#

On the shell. Does anyone have experience with these sticks? Help would be appreciated!

Thank you!
Ron

I would not use the HuaweiMode parameter. It's only for older devices.

Try the MessageContent from the original "12d1:1446" config file.

No, doesn't work either when I have it like this

Code: Select all


# ########################
# Huawei UMG1831
#
DefaultVendor= 0x12d1
DefaultProduct= 0x1446

TargetVendor= 0x12d1
I just get something like
[code]
 OK, driver found; name unknown, limitation of libusb1
 OK, driver "unkown" detached

SCSI inquiry data (for identification)
-------------------------
  Vendor String: HUAWEI  
   Model String: Mass Storage    
Revision String: 2.31
-------------------------

USB description data (for identification)
-------------------------
Manufacturer: Huawei Technologies
     Product: HUAWEI Mobile
  Serial No.: not provided
-------------------------
Warning: no switching method given.
-> Run lsusb to note any changes. Bye.

TargetProduct= 0x1404

You seem to have misunderstood. This is how the original config file looks like:

Code: Select all

########################################################
# Huawei, newer modems

DefaultVendor= 0x12d1
DefaultProduct=0x1446

TargetVendor=  0x12d1
TargetProductList="1001,1406,140b,140c,1412,141b,1433,14ac,1506"

CheckSuccess=20

MessageContent="55534243123456780000000000000011062000000100000000000000000000"

Use the line with the MessageContent parameter in your file - or just add "1404" to the TargetProductList and then use this file.

Hmm, doesn't seem to work, what I get:
I plug the stick into the usb port:

Code: Select all

# lsusb
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 005: ID 12d1:1446 Huawei Technologies Co., Ltd. E1552 (HSPA modem)
#

and I do a # usb_modeswitch -c /etc/huawei_modeswitch.conf
in the file huawei_modeswitch.conf I have:

Code: Select all

# cat /etc/huawei_modeswitch.conf 
######################################################## 
# Huawei, newer modems 

DefaultVendor= 0x12d1 
DefaultProduct=0x1446 

TargetVendor=  0x12d1 
TargetProductList="1001,1406,140b,140c,1412,141b,1433,14ac,1506" 

CheckSuccess=20 

MessageContent="55534243123456780000000000000011062000000100000000000000000000"
#

Ok, and when I do the modeswitch I see a bunch of messages flashing over my screen and I get a few Searching for target devices ... before it says

Code: Select all

  No new devices in target mode or class found

Mode switch has failed. Bye.

# lsusb
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 006: ID 12d1:1404 Huawei Technologies Co., Ltd.

but as you see, the device ID has changed from 1446 to 1404, so something has happened but not the thing we want

Thanks for your help!

Yes, that's exactly the thing we want!

USB ID has changed, so the mode switch was successful.

Now, if you have installed both the "usb-modeswitch" and the "usb-modeswitch-data" package, you can put your edited config file into "/etc/usb_modeswitch.d" which is the folder for custom/local configurations. Rename it to "12d1:1446" - and from then on everything should run automatically, including the binding of the serial driver which is the last step to make the modem work.

Edit: I just saw that your target ID, "1404" is still not in the TargetProductList. Please add it.

hm, okay, i've never used_modeswitch_data and see that it is compiled into my builddroot distro but for some reason i can't find the binary. So I guess i'll need to follow up on that first.... or is there an alternative way to get it going, without usb_modeswitch_data?
Where can I add my TargetProcutID to the list?
I didn't find anything on the main page...

Thanks,
Ron

Edit the config file with the long "TargetProductList" line. Add "1404" to the other IDs in the list.

The parameters in the config files are described in the device_reference.txt

I don't know your distribution at all, sorry. Where did you install usb_modeswitch from - was it a ready-made package or did you use the source code from here?

Yep, got it all working fine now, Thanks a lot!
