Hi
I am having problem with Sierra A312U modem in linux.
my linux is 2.6.27.45.
usb_modeswitch version 1.1.6.
i didnt load sierra driver. Option and usbserial driver is loaded in system.
Problem is that Modeswitch command is getting failed.
Now giving output of logs step-by step--
When modem is plugged in, the kernel messages are
Apr 13 18:09:58 (none) user.info kernel: USB Universal Host Controller Interface driver v3.0

I get clue from kernel logs that, somewhere interface error is coming.
and output of proc is

So please guide me how to move further.
Thanks in advance.
Your system is telling you the problem quite clearly: "invalid interface number". This makes the communication with the device impossible.
The question is: whose fault is it?
It might be:
a. the firmware of the device
b. the system (USB host, hard- or software)
It would help to use the device in a different hardware system with Linux on it and run the command "lsusb -v -d 1199:0fff" to see the interface details.

Sorry josh, i couldn't send you the lsusb interface details. Actually i am working on this modem remotely.
But my concern is usb_modeswitch command gets failed here.
Error: getting the current configuration failed (error -84). Aborting.
Below i am pasting you detail log.

So my modem didnt get switched.
But strange is that when i tried it with lower version of usb_modeswitch , it gets switched.

Although here also it is showing some error kinds of logs, but ultimately it gets switched.
So my question to you is, why the same thing is working perfectly in older version of usb_modeswitch utility and not in higher version(1.1.6) ??
kernel version is same 2.6.27 on my both testing.
I didnt test it with higher version usb_modeswitch-1.1.7. Do you think is it worth to test on higher version. Or should i stick to older version.
For sufferers of this modem on linux, i am giving my steps which gets ultimately connected.
Above after modeswitch, modem will get switched.
Then i tried to load the driver usbserial vendor=0x1199 product=0x68a3

But it was not enough to eat-up my bandwidth.
Because, wvdialconf or wvdial were getting failed.
#wvdialconf
Scanning your serial ports for a modem.
Port Scan<*1>: USB0 USB1 USB2 USB3
Sorry, no modem was detected! Is it in use by another program?
Did you configure it properly with setserial?
And at same time i get error in kernel log,
Apr 14 18:32:23 (none) user.err kernel: generic ttyUSB0: usb_serial_generic_open - failed resubmitting read urb, error -2
## wvdial
--> WvDial: Internet dialer version 1.41
--> Cannot open /dev/ttyUSB2: No such file or directory
Then i tried with option, but no luck.
Then i load sierra module.
But this module didnt get attached to modem. (i guess i should tried here /sys/bus/usb-serial/drivers/sierra/new_id, it may work...dont know)
But then after so unsuccessful tries i found on net
https://sierrawireless.custhelp.com/app ... Y1eWZKaHJr
Here there is some kernel-wise patch for sierra module.
I applied that patch for my kernel. sierra version: v.1.7.36
and then sierra module gets attached to this modem and after wvdialconf and wvdial both works perfectly.
I hope this will help others too.
Thanks.
But my concern is usb_modeswitch command gets failed here.

But it was not enough to eat-up my bandwidth.
Because, wvdialconf or wvdial were getting failed.
#wvdialconf
Scanning your serial ports for a modem.
Port Scan<*1>: USB0 USB1 USB2 USB3
Sorry, no modem was detected! Is it in use by another program?
Did you configure it properly with setserial?
And at same time i get error in kernel log,
Apr 14 18:32:23 (none) user.err kernel: generic ttyUSB0: usb_serial_generic_open - failed resubmitting read urb, error -2
## wvdial
--> WvDial: Internet dialer version 1.41
--> Cannot open /dev/ttyUSB2: No such file or directory
Then i tried with option, but no luck.
Then i load sierra module.
But this module didnt get attached to modem. (i guess i should tried here /sys/bus/usb-serial/drivers/sierra/new_id, it may work...dont know)
But then after so unsuccessful tries i found on net
https://sierrawireless.custhelp.com/app ... Y1eWZKaHJr
Here there is some kernel-wise patch for sierra module.
I applied that patch for my kernel. sierra version: v.1.7.36
and then sierra module gets attached to this modem and after wvdialconf and wvdial both works perfectly.
I hope this will help others too.
Thanks.

Sorry, I must have missed your last post.
There are lots of "84" errors in your log. They are likely caused by communication problems between your device and the system.
The meaning "Invalid or incomplete multibyte or wide character" refers to the device response following the command. So there is no way to know if the command was transmitted correctly.
The new command added in usb_modeswitch 1.1.6 will abort if an error happens. But in the case of error 84 the command may have reached the device nonetheless.
I have made a little patch against 1.1.7. Put it in the source directory and apply with "patch -p1 < ....".
See if that helps.

I guess you have missed my lines.
I have written all.
I tried with kernel-2.6.27's sierra.ko but it didnt binded as driver for that modem.
The reason i see here is that this modem's vendor-product id is not defined in sierra.c
[ But here i thought , i didnt try here by echo "vid pid" > /sys/bus/usb-serial/drivers/sierra/new_id .
It may worked. Right now i have no modem, otherwise i told you the result too. ]
Then i found from net that there is patch of sierra.c to support this modem.
I mentioned the link in my last post.
I used that, then it worked.

Hi josh
Thanks for your reply.
Unfortunately currently i dont have this modem right away.
I will arrange and will tell you the result.
But i have seen the patch. It is handling for error number of -84.
But if you see in my first post, there is error number -71 also.
I think when i fire modeswitch command first time it gives -71 and in onwards modeswitch command it gives -84.
This noted pattern is just my guesswork. May be wrong.
No worry, if this patch will work. But if not (may be due to -71 error number), then i will also check after putting -71 in or condition alongwith -84).
I will tell you the result.
Thanks again.
