I'm using Knoppix 3.4 and booting with knoppix26.
I have a USB2 CF card reader in a USB2 PCI port and can mount a CF card in the reader with no problem. But when I read lots of images from the card I only get USB1 transfer rates of about 700kB/sec. When I use the same reader in Windows I get around 2MB/sec. I'm new at this and am not sure what, if anything, can be done to get USB2 transfer rates from the reader.
This is what I get from dmesg | grep usb:
usbcore: registered new driver usbfs

and this is the relevant entry in /proc/bus/usb/devices:

and this is the line for the USB reader in /etc/fstab:
/dev/sda1 /mnt/sda auto noauto,users,exec 0 0
I changed the /mnt/sda1 to /mnt/sda to suit a program I wrote.
Is there something I can do to soup up the transfer rates?
And can I set up the entry in /etc/fstab so that when I put a card in the reader it is auto mounted?
Thanks
