I am using the K1 for development. It means need to connect to K1 from system like desktop or notebook for installing or data testing in K1.
Where can I download the USB driver for development purpose? In short, what tool do i need to sync up with a laptop?
LeTools is all you need if you're using Windows 7.
The file name in Lenovo support site is called Synchronization Software.
You should be able to install applications to K1.
For more info on not able to sync K1, you can refer to this article: Can't sync my K1 with my Laptop
