I can not do this via bur report because I could not select a valid package. I have researched this and was unable to find a solved case under exact condition. The issue was mostly discussed as an mtp or mounting problem, but I dug a bit farther into the problem. When it comes to a certain model, hardware is not even detected.
Thank you for all your dedicated work, Mo Following is the issue When connecting a "Galaxy S3 mini" via usb, it is not detected at all; however if connected during installation, it is temporarily detected as a "usb mass storage device" before CDrom is detected. Here are some general information about the system: # cat /etc/debian_version 9.6 # gcc --version gcc (Debian 6.3.0-18+deb9u1) 6.3.0 20170516 # uname -a Linux dreams 4.9.0-8-amd64 #1 SMP Debian 4.9.130-2 (2018-10-27) x86_64 GNU/Linux When Galaxy S3 mini is connected via usb: $ ls -l /dev /dev/mapper | grep brw-rw---- 1 root disk 254, 0 Dec 15 10:53 dm-0 brw-rw---- 1 root disk 254, 1 Dec 15 10:53 dm-1 brw-rw---- 1 root disk 254, 2 Dec 15 10:53 dm-2 brw-rw---- 1 root disk 254, 3 Dec 15 10:53 dm-3 brw-rw---- 1 root disk 254, 4 Dec 15 10:53 dm-4 brw-rw---- 1 root disk 254, 5 Dec 15 10:53 dm-5 brw-rw---- 1 root disk 8, 0 Dec 15 10:53 sda brw-rw---- 1 root disk 8, 1 Dec 15 10:53 sda1 brw-rw---- 1 root disk 8, 2 Dec 15 10:53 sda2 brw-rw---- 1 root disk 8, 5 Dec 15 10:53 sda5 brw-rw----+ 1 root cdrom 11, 0 Dec 15 12:39 sr0 l $ lsblk -o KNAME,TYPE,SIZE,MODEL gives KNAME TYPE SIZE MODEL sda disk 223.6G CT240BX200SSD1 sda1 part 243M sda2 part 1K sda5 part 223.3G sr0 rom 4.4G DVD+-RW UJ8A2 dm-0 crypt 223.3G dm-1 lvm 23.3G dm-2 lvm 9.3G dm-3 lvm 15.9G dm-4 lvm 1.9G dm-5 lvm 173G # mtp-detect libmtp version: 1.1.13 Listing raw device(s) No raw devices found. # ls -l /sys/bus/usb/devices/ total 0 lrwxrwxrwx 1 root root 0 Dec 18 11:24 1-0:1.0 -> ../../../devices/pci0000:00/0000:00:1a.0/usb1/1-0:1.0 lrwxrwxrwx 1 root root 0 Dec 18 11:24 1-1 -> ../../../devices/pci0000:00/0000:00:1a.0/usb1/1-1 lrwxrwxrwx 1 root root 0 Dec 18 11:24 1-1:1.0 -> ../../../devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1:1.0 lrwxrwxrwx 1 root root 0 Dec 18 11:24 1-1.5 -> ../../../devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.5 lrwxrwxrwx 1 root root 0 Dec 18 11:24 1-1.5:1.0 -> ../../../devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.5/1-1.5:1.0 lrwxrwxrwx 1 root root 0 Dec 18 11:24 1-1.5:1.1 -> ../../../devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.5/1-1.5:1.1 lrwxrwxrwx 1 root root 0 Dec 18 11:24 2-0:1.0 -> ../../../devices/pci0000:00/0000:00:1d.0/usb2/2-0:1.0 lrwxrwxrwx 1 root root 0 Dec 18 11:24 2-1 -> ../../../devices/pci0000:00/0000:00:1d.0/usb2/2-1 lrwxrwxrwx 1 root root 0 Dec 18 11:24 2-1:1.0 -> ../../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1:1.0 lrwxrwxrwx 1 root root 0 Dec 18 11:24 2-1.2 -> ../../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 lrwxrwxrwx 1 root root 0 Dec 18 11:24 2-1.2:1.0 -> ../../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 lrwxrwxrwx 1 root root 0 Dec 18 11:24 2-1.5 -> ../../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.5 lrwxrwxrwx 1 root root 0 Dec 18 11:24 2-1.5:1.0 -> ../../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.5/2-1.5:1.0 lrwxrwxrwx 1 root root 0 Dec 18 11:24 2-1.5:1.1 -> ../../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.5/2-1.5:1.1 lrwxrwxrwx 1 root root 0 Dec 18 11:24 2-1.8 -> ../../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.8 lrwxrwxrwx 1 root root 0 Dec 18 11:24 2-1.8:0.0 -> ../../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.8/2-1.8:0.0 lrwxrwxrwx 1 root root 0 Dec 18 11:24 2-1.8:0.1 -> ../../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.8/2-1.8:0.1 lrwxrwxrwx 1 root root 0 Dec 18 11:24 usb1 -> ../../../devices/pci0000:00/0000:00:1a.0/usb1 lrwxrwxrwx 1 root root 0 Dec 18 11:24 usb2 -> ../../../devices/pci0000:00/0000:00:1d.0/usb2 #lsusb | sort Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 8087:0024 Intel Corp.
