Bug Description

Modem switches fine in USB2 ports, but when connected to USB3 port, it does not work.

The log says it is switching:

Apr 12 10:42:11 marius-T1005 usb_modeswitch: switching device 19d2:0166 on 006/0
02

but the USB device ID does not change:

Bus 006 Device 002: ID 19d2:0166 ZTE WCDMA Technologies MSM

When connected to a USB2/combined USB2/eSata, it gives:

Bus 001 Device 036: ID 19d2:0167 ZTE WCDMA Technologies MSM

and working modem.

The only thing sticking out is the somewhat "non-mainstream" message content. No other (ZTE) device is using this.

I'd suggest trying with the mainstream ZTE command (basically an EJECT):

- Extract the "19d2:0166" file from /usr/share/usb_modeswitch/configPack.tar.gz

- Put it into /etc/usb_modeswitch.d and edit it

- Replace the existing MessageContent line with these:

MessageContent="5553424312345678000000000000061e000000000000000000000000000000"

Josua: using that switch message, it does not even switch in the USB 2.0 port.

Maybe there is a slightly different way to access USB 2.0 devices in a USB 3.0 port? Or a bug in libusb or the kernel driver.

Re-addressing this issue after a busy while.

Your usb_modeswitch log from a successful switch is indicating that your installation is using "libusb 0". This follows from the fact that the name of the bound driver ("usb-storage") is reported. "libusb 1" is not able to do this.

Can you try to compile the core binary of usb_modeswitch with "libusb1-compat0-dev" instead?
I'm not sure how it's exact name is on your system. It is a wrapper library to compile programs written for libusb0 with libusb1, without requiring any changes. It should replace "libusb0-dev".

Hmm, I see no compat package in Ubuntu, just:

libusb-0.1-4
libusb-1.0-0

$ ldd /usr/sbin/usb_modeswitch
 linux-gate.so.1 => (0xb779e000)
 libusb-0.1.so.4 => /lib/i386-linux-gnu/libusb-0.1.so.4 (0xb7773000)
 libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xb75ce000)
 /lib/ld-linux.so.2 (0xb779f000)

Is it not possible to build it with 1.0.x?

Don't know why Ubuntu does not have it.

I opened bug #991004 to have the compat package in Ubuntu. Then installed it manually as described there. Now I have:

so the compat version in /usr/local/lib is used, but it still fails:

I have encountered several cases lately where timing issues surfaced. I'm wondering if this may be connected to the spreading of 3.0 ports.

If you want to test, add the "WaitBefore=<n>" parameter to your custom config file. The value is in seconds - I'd start with 8 or so, decreasing it in case of success.

Unfortunately that did not help either, even with "config: WaitBefore set to 20". But it might be a tip to improve stability of the use of the modem in other USB ports.

You might try the "ResetUSB=1" parameter. This will issue a reset command after completing the message transfer.
Somewhat unsubtle and just a shot in the dark, but who knows?

I just hope we did not encounter an issue with the xhci driver ...

I didn't have time to test another kernel as requested higher in the thread, but I found a workaround in the usbmodeswitch forums :

http://www.draisberghof.de/usb_modeswitch/bb/viewtopic.php?t=960

The idea is to "extract" the the configuration file from the collection in /usr/share/usb_modeswitch and then switch "manually" the modem.

For my modem, I took the file "12d1:1505" and made a small script to make the operation easier :

#!/bin/sh
/usr/sbin/usb_modeswitch -I -W -s 10 -c "12d1:1505" -v 12d1 -p 1505

Now all I have to do to switch the modem is : sudo ./switch

That's it !

Wessel Dankers (wsl) wrote :

Based on Christophe's post I modified /lib/udev/usb_modeswitch to wait for a number of seconds before running the modeswitch_dispatcher. Some experimenting determined the minimum number of seconds to be 11. My modem is now detected and switched automatically, even if I have to wait a few seconds longer than usual.

Obviously this is not a real solution but it might point someone more knowledgable in the right direction.

Patch attached.

Marius B. Kotsbak (mariusko) wrote :

It is actually working with command line, so I think the bug is in usb_modeswitch and not in the kernel.

But why is it working? Could it be that the modeswitching is started before the device is ready after it has been inserted? The "-I"switch is required for it to work. Without "-s 10" it still switches, but it gives error messages and indicate it failed (but running it again says there are no switchable devices).

There might be a loose relation to bug #992639, where the storage driver attribute "delay_use" has some relevance:

https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/992639

Anyway, all these timing problems seem to be rather system-specific. Apart from pointing to the tweakable parameters (like "WaitBefore" in the usb_modeswitch config files and "delay_use" for the usb-storage driver), I'm at a loss about how to tackle these issues *generally* ...

What about adding retries when the switching fails?

Revision history for this message
Wessel Dankers (wsl) wrote :

So, it looks like usb-storage wants to have the device from t+1 until 1+11 (counting from the moment of insertion). usb_modeswitch wants to detach usb-storage at t+1 (exact numbers differ per chipset, apparently). This looks like a race condition, caused by various parties coding in arbitrary delays instead of using an event-based mechanism.

Pure speculation of course, but if this is really the root cause it would be nice if the usb-modeswitch people and the usb-storage people could agree on some sort of api to do this properly and without racing.

Revision history for this message
Josua Dietze (digidietze) wrote :

There is nothing orderly about the whole mode-switching business. From the system's view it's no different than a physical unplug and reinsert of a device. The word "API" does not come to my mind at all.

For usb_modeswitch as such, timing is not important - in theory. The tipping point *should* be the driver detachement that is done by libusb. In my simple thinking, I expect to have full control over the device from then on. I can obviously send and receive data and control messages. So how can the system keep a hold of the device?

There is one more idea to check. What if the system is grabbing the device again *after* the switching message was issued and the device handle is released? Can it be that the 3.0 driver is just so fast (or "clever") that it re-owns the device immediately?

To test this, there is a parameter called "ReleaseDelay" that will cause usb_modeswitch to hold the device under its control for any number of milliseconds. One modem family (BandLuxe) actually requires this to complete the mode switch.

BTW, I just tried my whole modem collection (9 sticks!) on Ubuntu 12.04 x64, up to date, in the only USB 3.0 port that I have. Neither a delay_use of "1" nor one of "0" caused any disruption at all. So I'm still sure there is some hardware involved in this.
See the xHCI errors in the logs above, even when using the standard "eject" tool.

Unfortunately, this means that I have no way to help with testing ...

People,

I need *anybody* with the USB 3.0 problem test the "ReleaseDelay" parameter.

If that does not work, there is still plan B which is to alter the default "delay_use" option with the installation of usb_modeswitch. I can also let it check the setting with every run.

This would of course affect all devices using usb-storage, so I'd prefer an 'internal' solution.

12.10 is moving closer and I'll be off travelling in October, so I need a report *soon*.

Josua Dietze (digidietze) wrote :

Here is a little HowTo for conducting the test I requested:

There is a list (OR a package) of small config files in
/usb/share/usb_modeswitch.

Pick the one that matches your stick's ID in *install mode* (e.g. if the mode switch fails or if switching is disabled globally in
/etc/usb_modeswitch.conf).

Copy that file to "/etc/usb_modeswitch.d". It will now be preferred over the one in the default location.

Edit it and add a line:

ReleaseDelay=3000

This will make usb_modeswitch keep the device handle for 3 seconds after sending the switching command.
No guarantee, but it's worth a try.

If there is any effect, smaller values could be tested.

O.K., so the usb_modeswitch package should install a file in "/etc/modprobe.d" named "usb-storage.conf" with this content (or so):

--x--
# Increase the default delay to avoid conflict with usb_modeswitch

options usb-storage delay_use=3
--x--

Is there a way to check if there are other packages which set options for this module?

Also, the next program release will contain a check/set of the module attribute, so the mode switch would fail only once, even if the delay wasn'n pre-set.

Pushing a file to change these settings with usb-modeswitch is not the right way to fix this. Instead, it's something that should be looked at directly by the kernel developers and change the timeout if it needs changing.
