Subject: scsi error "sense key: No Sense" with usb flash drive
Date: Thu, 08 Sep 2005 01:13:54 +0200	[thread overview]
Message-ID: <431F7432.2090004@gmx.net> (raw)

Hi,

upon insertion of my new 2048 MB usb flash drive, the kernel
(vanilla 2.6.13) spat out the following errors:

This error only happens with this specific flash drive.

Is this just a quirky usb flash drive or do the errors indicate
a bigger problem?
