Bought two MID7015's in the last two days. First one I set USB Debugging on and then tried to connect to Windows XP machine. No USB icons on Notification Bar on the Kyros and WinXP complained that "USB Device Not recognized". Turning off USB Debugging and rebooting the tablet and PC did not help. Called Coby Support and after having me reset the device using the reset button on the back and also going to the Privacy menu in settings and resetting the device, the result was the same. Tech Rep said to return the device as it was faulty. Got a new tablet. Connected successfully to the PC first time out of the box. Turned on "USB Debugging" and could not connect. Turned it off and still could not connect. Rebooted both the tablet and the PC. Still the same fault. Seems that as soon as you enable "USB Debugging" that it somehow disables successful connection to a PC. My main interest in the tablet is to be able to sideload an app of my own design, so the USB interface is especially important. Called Coby again and the escalated to level 2. No reply from them yet.
