windows, and i tried an ubuntu vm same result! after connecting it for about a minute it gives: usb device not recognized, then disconnects, then appears the message that i'v posted for a few second then it shows the mydocs folder for a few more seconds then it shuts off. i pressed the power button for more than 10 sec, then tried to press very shortly and i get no blink, so i thought i might be the battery is flat.
this is the 1st time i use this usb cable, it's a samsung U2. could this be a problem, i though it should be compatible with all usb cables.
