I should say that I installed a separate USB 2 pci hub. Here is how usbview sees that (kinda cute how the "manufacturer" is my kernel version :)):

NEC Corporation USB 2.0
Manufacturer: Linux 2.4.21-pre5 ehci-hcd
Serial Number: 00:0a.2
Speed: 480Mb/s (high)
Number of Ports: 5
Bandwidth allocated: 0 / 800 (0%)
Total number of interrupt requests: 1
Total number of isochronous requests: 0
USB Version:  2.00
Device Class: 09(hub  )
Device Subclass: 00
Device Protocol: 01
Maximum Default Endpoint Size: 8
Number of Configurations: 1


And here are the relevant parts from usbview for the devices on the hub:

EPSON Scanner
Manufacturer: EPSON
Speed: 480Mb/s (high)
USB Version:  2.00
Device Class: ff(vend.)
Device Subclass: ff
Device Protocol: ff
Maximum Default Endpoint Size: 64
Number of Configurations: 1
Vendor Id: 04b8
Product Id: 0112
Revision Number:  1.01

ImageMate 6 in 1
Manufacturer: SanDisk Ltd
Serial Number: 101026105633
Speed: 480Mb/s (high)
USB Version:  2.00
Device Class: 00(>ifc )
Device Subclass: 00
Device Protocol: 00
Maximum Default Endpoint Size: 64
Number of Configurations: 1
Vendor Id: 0781
Product Id: 0621
Revision Number:  0.05

I had to setup the scanner in /etc/sane.d/epson.conf but the card reader Just Worked with the following in /etc/fstab:

/dev/sde1               /mnt/flash1             auto    noauto,owner,kudzu 0 0

I have another Usb 1.1 card reader as /mnt/flash so the USB 2 one is seen as /mtn/flash1.
