When my card was plugged into another PC it gave another three lines of 
output (as I remember it). Maybe Jethro remembers this.

Rosemary suggested:

I already have acpi=on in my grub menu.lst file for Mandriva:
kernel (hd0,6)/boot/vmlinuz root=/dev/hda7 acpi=on noapic 
resume=/dev/hda5 splash=silent vga=788

Daniel suggested this:
[root at pizza grub]# mkdir /media/usb0
[root at pizza grub]# mount -o sync,noatime,umask=000 /dev/sda1 /media/usb0
mount: you must specify the filesystem type
[root at pizza grub]# ll /dev/sda1
ls: /dev/sda1: No such file or directory

Jethro asked:

No. I have had the card only a few months, so I haven't tried it on 
older distros. On the other hand my Sony digital camera (with the same 
Memory Stick) can download via gThumb using PTP protocol - no problem!

I suspect that this is part of the problem. Is it that the software does 
not have the necessary parameters or drivers for ASUS?
It is still not working.

Thanks everybody.
