the data traveller can run on either host of guest(that what i think) anyway to make it work plug the usb to your host when it detects it go to VM --> Removable Devices - > USB click on Removable disks it will give a message that you need to safely remove the device from the host do not click OK yet right click on the safely remove icon on your host and safely remove the usb from your host ...when this is done click the ok message in the guest it will start to pick up the Vmware usb drive install that (choose the automatic install option) when the driver is installed it will show the usb in the guest

Did you plug in the drive when the guest had focus?

Well in that case I suspect you have been bitten by the Suse bug.

Its not a bug actually, Its just that opensuse dropped /proc/bus/usb/
in favor of /dev/bus/usb

See this thread on Novell's bugzilla:
https://bugzilla.novell.com/show_bug.cgi?id=210899

There is allegations that /proc/bus/usb/ is insecure, but that Vmware refuses to change to the new standard.

In the end, it seems that the suse Kernel maintainer was brow beaten into providing a way to turn on the old method of usb support but it might not yet be in your kernel.

If your kernel is new enough, you can try as root:
mount -t usbfs none /proc/bus/usb/

I am not exactly sure which kernel it re-appeared in, or if vmware has finally decided to support the new method now that a couple other distros have also followed Novell's lead on this item.

It took the community a month to force Novell to re-enable this, but in the end, it really is a Vmware issue because the old method is in fact insecure.
