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

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.

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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/979697 Title: Modeswitching modem not working with some USB 3.0 host controllers To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/979697/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 979697] Re: Modeswitching modem not working with some USB 3.0 host controllers
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.
