I think it is the fast boot not working as it keeps on saying: Failed (command write failed (Unknown error)). So I have to unplug it and put it back in to another port to work. However, even with this error, fastboot devices returns the device number.
Is there a way to fix this problem or is it a fault with the netbook, tablet or cable?
