I am trying to get my Zaurus sl-c1000 (Running pdaxrom, beta2) to work with a usb hub, I can get it to work with the hub as long as I only have one usb memory stick plugged into it. If I have both my memory sticks pluged into it it doesn't display either.

Has anyone else got multiple memory sticks working on their zaurus?

Also how do I tell the zaurus that I want to eject the memory stick (I know that it is documented somewhere but I can't seem to find it)

Get a powered usb hub... the Zaurus can't power to many devices

Well make that more then 1 device... and it has to have very low power requirements

Haven't tried more than one USB sticks plugged in at the same time. A single USB memory stick will be mounted from /dev/sda1 to /mnt/usbstorage. So to unmount a simple "umount /mnt/usbstorage" will do.
I am also curious to know how multiple memory devices (USB sticks, HDDs, etc) can be mounted at the same time.
How does df or dmesg show when both sticks a plugged? How about one single stick with hub? Or just the stick without the hub?

Ok I have got it working I just needed to add the lines in to /etc/fstab that will mount /dev/sdb1 and /dev/sdbc1. Then when I have inserted the usb memory stick I just mount the next device (not sure how to do this automatically yet).

Oh and I have plugged the power into my hub which I think has also made a big difference.

I have been reading up on this (documentation seems to be very scarce for this sort of thing.). I think that I will need to rewrite usb-storage script because at the moment it just tries to mount to the one directory.

have a look at the usb-storage script in my automounter package. it does try to find 4 usb disks and mount them if they are available. my usb hub has 4 connections and that's why I hardcoded it at 4 devices if you are wondering why 4 and not more or less.
