I have a issue with my usb stick on linux: it is detected in lsusb but not as a disk: there is no entry in fdisk -l, programs like Gparted or Gnome-Disk don't recognize it either
This means it is not the commom problem that I could solve with mount
When I run lsusb the entry for this device is:
Bus 002 Device 005: ID 13fe:4300 Kingston Technology Company Inc.
When I run dmesg | grep -i usb

When I run cat /sys/kernel/debug/usb/, this device is showed this way:

What I found interesting the device is recognized as usb-storage and as UsB Disk
Notes
- As I pointed above, Gparted doesn't recognizes the device
- There is no entry of this device in
fdisk -l - This is not a problem solved with
mount - Other Usb Sticks devices works fine
- This device works fine on Windows
- The problem occurred in Ubuntu and Mageia
EDIT
Partially worked:
- I started VBox and trying to connect the usb stick in the guest (recognized as usb but not as a disk in linux guest)
- After disconnect from VM the host Ubuntu could detect and mount automatically the usb
If I unplug the usb device and try to plug it again, it doesn't recognizes it anymore
