Hi mcamou, i have a c860 with cacko 1.21. I found this problem as well. Here\'s my solution which seems to work. It seems to happen after i reboot (only have it two days yet btw!). The solution is, plug in the usb cable, set the option to tcp/ip and click okay. Then go back in and select the sd/cf card and click okay. My Z comes up with a dialog saying usb alert. now plug out the cable click okay and plug the cable in. it should work now. will work as long as you don\'t reboot. if it doesn\'t work, i\'ll check it further.
