I can no longer mount my Sony Walkman MP3 player on latest Tumbleweed. I'm not quite sure when it stopped working but I used to be able to plug it in and 2 options used to pop up under removable devices (Plasma Desktop): Mass storage (Storage Volume) and MTP (Portable Media Player) entries used to allow me to "Mount and Open" which would then open a Dolphin window with the root directory of the device. Everything now happens the same up to and including the Dolphin window opening, but almost immediately, the directory shown is /, not the device. The device no longer shows up as a mass storage. I no longer have the option of mounting it as a mass storage device. the MTP option is present, but the results are the same. Dolphin window opens, but the MP3 player is not mounted. Here is the relevant lines from dmesg. Any advice on how to figure out what is happening? I guess the interesting lines are these 2: [ 156.119906] blk_update_request: I/O error, dev sdc, sector 4 op 0x1:(WRITE) flags 0x0 phys_seg 1 prio class 0 [ 156.119912] Buffer I/O error on dev sdc1, logical block 1, lost async page write I have formatted the device through its menu system. connecting it to a Windows machine shows no issue and allows me to move files to it.
