USB Stick CS-D too slow since kernelupdate

[m_0_r_0_n]

Hi,
my usbstick is too slow since the update of the kernel. It takes 5 minutes to copy a 8 MB file to the stick. The admin tool "usbview" displays the following information

Any idea how to speed up the writing processes?

Is the device still showing up as a SCSI device? (/dev/sdX)
Could be that in the upgrade the Low Speed USB storage driver was enabled. (devices would be /dev/ubX)

Is the device mounting with the sync option?
(Post the output of mount as root.)

Can you post the relevant section of dmesg after you plug the device in also?

[m_0_r_0_n]

[Headrush]

It's the sync option slowing it down.

Are you using fstab entries for this device? What DE/mounting system are you using?

[m_0_r_0_n]

Yes, but I don't know where I got this settings from. I think I ve copied them from another fstab file long time ago.

/dev/sda1 /mnt/usbstick vfat rw,noauto,user,exec,sync,uid=1000 0 0

I ve changed it to

/dev/sda1 /mnt/usbstick vfat rw,noauto,user 0 0

The write process is much faster again :-) How can the device be mounted automatically when plugging the stick in?

To (un-)mount the device I always enter the commands mount /mnt/usbstick and umount /mnt/usbstick in the bash console. I am using Gnome as deskop environment.
