[Lilux-help] USB

HI After a while working with my USB-Memorystick, it will not be mounted anymore. While copying, the error message appears: .... does not exist anymore. I then unplug the USB Stick and plug it again, and after a while, it works again. I use SuSE 9.2 on a 550MHz Pentium III. The Stick is recognised as (lsusb) Bus 001 Device 011: ID 067b:2516 Prolific Technology, Inc. Bus 001 Device 010: ID 067b:2515 Prolific Technology, Inc.
