[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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/755342 Title: Samsung Xcover 271 B2710 mass storage does not mount automatically To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-modeswitch/+bug/755342/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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.

[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. I have not seen problems like this with the original (upstream) package which is also used on Debian.

Addendum: Due to the way usb_modeswitch works, the udev rules line WILL match with all devices using the Samsung ID, but the dispatcher mechanism will NOT start the switching process except for the U209 modem.

No reply from the original contributor, but I finally found this usb_modeswitch output via Google, after several fruitless attempts: Received inquiry data (detailed identification) - Vendor String: SAMSUNG Product String: SCH-U209 Install Revision String: 2.31 - Device description data (identification) - Manufacturer: SAMSUNG Electronics Co.,Ltd. Product: USB MMC Storage Serial No.: 0002 - The page is here, see post #14: http://forum.ubuntu-fr.org/viewtopic.php?id=370414 I consider this information correct; this enables us to identify the modem apart from the phones. I think I can assume that the USB ID strings are not specific to the modem, so the SCSI strings need to be used. The file "/usr/share/usb_modeswitch/04e8:f000" has to be renamed to "/usr/share/usb_modeswitch/04e8:f000:sMo=U209". This should do the trick and leave other Samsung devices alone.

The instant "fix" is O.K.

[Bug 755342] Re: Samsung Xcover 271 B2710 mass storage does not mount automatically
Confirming the fix by Michael B also works with a Samsung S5510.
The problem is with usb_mode_switch and the associated udev rules in
/lib/udev.d/rules/40-usb_modeswitch.rules:
# Samsung U209
#ATTRS{idVendor}=="04e8", ATTRS{idProduct}=="f000", RUN+="usb_modeswitch
'%b/%k'"
These lines do not represent a unique product; the Samsung Xcover 271
B2710 and Samsung S5510 (and others??) also match this line (lsusb gives
04e8:f000).
Commenting out this line fixes the problem on the Samsung 5S5510, and I
would guess the Xcover 271 B2710 too.
