Hello, I usually put the RS-MMC card to a RS-MMC reader and connect the RS-MMC reader to my Linux laptop with USB. It automatically mounts to the "Places" -menu in Gnome (I am using Ubuntu Dapper and Gnome 2.13.2 but it works similarly also in older versions, it worked fine already on Hoary and Breezy). In KDE it may be different and you might end up hand-mounting it from console (I have done that with some past Suse version, I have used versions 9.0, 9.1, 9.2, 9.3 so far and I am going to install soon the 10.0). However, with a quite up to date Linux you should not have any problems with mounting. I don't mount the 770 directly (so that the card would be inside the device) because my 770 is usually in usb-host-mode because I use to connect a USB-network adapter to the USB of 770 (there is obviously a powered USB hub in between a USB gender changer adapter). If you don't have a card reader, I think it would be a good investment to do. They are failly inexpensive and support a wide variety of cards, like SD, MMC, RS-MMC, Compact flash etc. Best Regards, Karoliina Salminen
