[Desktop-packages] [Bug 755342] Re: Samsung Xcover 271 B2710 mass storage does not mount automatically
This bug still exists in Kubuntu 20.04. Samsung Xcover B2710 isn't connected properly. Long ago I fixed it on Ubuntu 12.04 by "DisableSwitching=1" and forgot about it. Now found this bugreport once again and old fix still works. If my help is needed in debugging of this issue, I'm ready. P.S. Does this disabled switching affects other USB devices somehow or only mobile phones? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to usb-modeswitch in Ubuntu. https://bugs.launchpad.net/bugs/755342 Title: Samsung Xcover 271 B2710 mass storage does not mount automatically Status in usb-modeswitch package in Ubuntu: Fix Released Bug description: Steps to reproduce: 1.

Only as an update: As of today, it still doesn't work out of the box. The workaround fixes it. Allow me a bit of comment that sounds sarcastic, and yet bugs me as an oldtimer with 20 years on Linux: I always advocate FOSS. Should someone hit this snag, how can I honestly defend this shortcoming? Asking Aunt Tilly to search Google and end with her using the CL to vi a parameter in a file? Could I blame her on going back to the monopolist? I would defend my beloved Linux, were she the first to encounter this. Alas, it has been around for > 5 years.

[Desktop-packages] [Bug 755342] Re: Samsung Xcover 271 B2710 mass storage does not mount automatically
Yes, it's correct to disable mode-switching when checking out the SCSI attributes. This is what usb_modeswitch sees when a phone/modem is plugged in. Then it has to determine if any action is required. Bottom line: The dispatcher part of the usb_modeswitch Ubuntu fork has trouble reading the SCSI attributes, which are however present and readable.

[Desktop-packages] [Bug 755342] Re: Samsung Xcover 271 B2710 mass storage does not mount automatically
The problem is obvious in the log from #14: Warning: SCSI attribute vendor not readable. Warning: SCSI attribute model not readable. Warning: SCSI attribute rev not readable. The filter sMo=U209 which should prevent usb_modeswitch from doing anything in this case does not work - because the SCSI identification fails. The problem is in the dispatcher part of the Ubuntu fork of usb_modeswitch. ikletti, can you check out these SCSI attributes in the /sys tree when your phone is plugged in?

Regarding comment #8. Can now confirm that usb_modeswitch is not working with Kubuntu 12.04. Changing the config file to 'DisableSwitching=1' provides a fix. Have enabled debugging (EnableLogging=1) and collected debugging information with 'DisableSwitching=0'. File is attached. ** Attachment added: usb_modeswitch.log https://bugs.launchpad.net/ubuntu/+source/usb-modeswitch/+bug/755342/+attachment/3399845/+files/usb_modeswitch.log -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to usb-modeswitch in Ubuntu. https://bugs.launchpad.net/bugs/755342 Title: Samsung Xcover 271 B2710 mass storage does not mount automatically Status in “usb-modeswitch” package in Ubuntu: Fix Released Bug description: Steps to reproduce: 1.

[Desktop-packages] [Bug 755342] Re: Samsung Xcover 271 B2710 mass storage does not mount automatically
I can confirm that the fix in ubuntu 12.04 does not fix the connection problems of a Samsung B2710 mobile phone. The phone is recognized by the kernel but does not show up as a usable device (the device file will not be created). (USB mass storage mode) After setting DisableSwitching=1 in /etc/usb_modeswitch.conf device is working as expected.
