USB stick problem (windows FAT32 formatted)

Hello,

I’m on Tumbleweed with kernel 3.15.8-44.g258e3b0-xen.
I try connecting an Iomega USB stick of 512MB FAT32 formatted on windows 7: readable and writable on the Window system.
On Opensuse tumbleweed and KDE I cannot connect.
The KDE Notify plasmoid is flickering and unusable
If I let the stick on the system after some time the whole system is locked and I must hard reset the system

In /var/log/messages I see these info when connecting

The last warning is constantly repeated.

when I remove the stick I see the next messages

Another stick (formatted under Unix) is working correctly but it is not recognized under Windows
With this stick I see these message

I have reformatted the Iomega Stick under windows but the problem remains.
I think that this can maybe related to the fact that the the stick is seen as a disk without partition. Problem: I cannot change the formatting setup on Windows
I used this stick some time ago with an older kernel.

Any Idea how to solve this problem?
