Thanks for the lsusb output confirming our earlier assumptions. It shows the alternate setting with 3 endpoints as expected, and it shows that we have all the necessary CDC functional descriptors. Including a Union descriptor with master and slave pointing to the same interface. Which is as correct ...

I have asked Bjorn Mork to come over and see if he can add the missing piece. It might be that NetworkManager needs ModemManager for bringing up the connection. Yes, it does. Install a reasonably recent ModemManager and this should Just Work(tm) And now that all the hard work of writing code and te...

My conclusions: The initial 55534243 is the mandatory prefix for modeswitch messages the stuff from after 55534243 to before 1106 is irrelevant. (leading 12345678 or all zeroes, trailing "a" or "6" has no effect) See http://www.usb.org/developers/docs/devclass_docs/usbmassbulk_1...

Oh is it ... so this is how the linux nether world thread looks like ? i guess noobs like us can't be part of it ? ... No, no, of course you can. Anyone can take part. Note that we are all "noobs" here. I just wanted to accellerate the process a bit, since I knew pretty well what to do. S...

oh ... ok ... will wait for your instructions to unbind/bind by device to the right drivers after you get back home. Like i said i am not so adept in understanding things under the hood ... superficially i can only grasp the concept. To manually switch the modem to other drivers, you first have to ...

I just tried updating/upgrading all the qmi and modemmanager packages but they were already up to date as I am using the very latest CentOS 7 x86_64 (1511). CentOS will never be "up to date" wrt packaged software versions. It is based on RHEL. The major versions of all packages are frozen...

Yes, it's working. I deleted for sure compiled cdc_mbim.ko, then: modprobe cdc-wdm insmod /home/hippo/Downloads/linux-4.5-rc5/drivers/net/usb/cdc_ncm.ko modprobe cdc_mbim Thanks! Good to know that we didn't need that quirk after all. I'll do a bit more testing of the other fix, and then try to get ...

Damn.. it was my fault. I changed DisableSwitching=0 instead of DisableMBIMGlobal=0 :) But now.. it's ... wait for it... wait for it.. working! Even I can ping the internet :) Great! Could you repeat the test without your first patch (the NDP-to-end quirk)? I just got at report that the K5160 works...

Hi, oh, I should see that yesterday.. my fault also :) What it should do now? Should I be able to connect via normal LTE or it should be do ethernet bridge even if DisableSwitching=0? (because it did eth bridge) Mar 03 08:44:39 arch kernel: usb 3-2: new high-speed USB device number 11 using xhci_hc...

Hi, patched, recompiled, loaded.. but again I connect to carrier, but no ping at all to nothing (internet, gw, dns). Shit. I was really hoping that this was the last piece of the puzzle. Well, thanks a lot for the quick testing. Don't know what else to test. EDIT: One thing just occured to me: The ...

Feb 25 20:04:18 arch kernel: cdc_mbim 3-2:2.0: NDP will be placed at end of frame for this device. That's good. Your changes to the driver did what they were supposed to do. OK, so I just got an E3372 today with the exact same problem. It requires the NDP-to-end quirk (which is already applied sinc...

Hi, thanks! Now adding module working as should :) but (actually, I already forget what should work now..) The idea was to test if the "NDP at end of frame" quirk would make a difference. But it doesn't look like that was the problem. Or at least not the only problem. Feb 25 20:04:18 arch...

Yes. I assumed cdc_mbim was already autoloaded, and therefore also the modules it depends on.

Try

Hm.. dont want to compile whole kernel, so I just need to download usb_modeswitch, edit mbim_devs and compile it? :) No, you need to compile the cdc_mbim driver. Which doesn't necessarily mean the whole kernel, but it means that you need to be set up for building drivers. I don't know how arch does...
