I previously had been using a generic PCMCIA CF adapter on my laptop in combination with a nice shscript I wrote for dumping the photos from it as well as some other things. I upgraded my CF card to a 4GB microdrive and consequently needed something that would transfer more quickly, this device was the answer, except it seems to not work under linux.
#Edit: I posted a url to the device but was censured. if you go to the obvious domain name for delkin(delkin[dot]com), and add delkin_products_adapters_cardbus.html to the root web folder you'll get the URL. Sorry for the mess on that one, and I understand the spam problem.

My distribution is SuSE 9.0 Pro recently upgraded to 9.1 with kernel 2.6.4-54.5-default

I followed the what-to-post sticky, good idea to put that post at the top of the forum, saved me the question of asking "what shall I give you?".

I am pretty desperate because now I have to boot this machine to windows to dump my 4GB microdrive full of photos which makes me a relatively unhappy camper. Delkin, the manufacturer, expressed relative disinterest in helping, I hear their OSX Driver works but has some quirks.

Let me know if there is anything you would like to know and I will do my best to answer. Thanks for providing this wonderful forum, google has found many answers for me here in the past but this I think is my first time asking a question directly !

Cheers,
