usbfs: process <pid> (mtp.so) did not claim interface 0 before use I get this error message on ubuntu 18.4. I believe there are two different problems.
First problem could be that InternalSD is readonly to the MTP process on the phone (see last line in log), why? Read-only requests worked. The other problem are the failed read attempts with varying errno, see below. Log from phone is: 05-28 15:32:02.505 D/MtpService(3263): Adding MTP storage 0x10001 at /storage/emulated/0 05-28 15:32:02.505 D/MtpService(3263): Adding MTP storage 0xa5bf0001 at /storage/7743-14FD 05-28 15:32:02.505 D/MtpService(3263): starting MTP server in MTP mode with storage /storage/emulated/0 disabled 05-28 15:32:13.094 E/MtpServer(3263): request read returned -1, errno: 5 05-28 15:32:13.551 D/MtpService(3263): starting MTP server in MTP mode with storage /storage/emulated/0 05-28 15:32:13.558 D/MtpService(3263): Adding MTP storage 0xa5bf0001 at /storage/7743-14FD 05-28 15:32:13.558 D/MtpService(3263): Adding MTP storage 0x10001 at /storage/emulated/0 05-28 15:32:26.711 E/MtpServer(3263): request read returned -1, errno: 5 [ above repeated several times. ] 05-28 15:35:30.269 D/MtpService(3263): Adding MTP storage 0xa5bf0001 at /storage/7743-14FD 05-28 15:35:30.270 D/MtpService(3263): Adding MTP storage 0x10001 at /storage/emulated/0 05-28 15:35:53.914 E/MtpServer(3263): deletePath stat failed for /storage/emulated/0/DCIM/Camera/IMG_20180519_202734.jpg: No such file or directory [repeated for each file] -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/1700649 Title: MTP device fails to mount To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/1700649/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
