I got a new laptop with USB 3.0 port. I can use USB 2.0 to download code. The max speed is 38.1MBS.
But I cannot switch to USB 3.0 port on same laptop. USB3.0 can download firmware. But it does not recognize my firmware. Even I download firmware by USB 2.0-only port then switch to USB 3.0 port nothing will happen.
Laptop is Lenovo X230. OS is windows 7 professional(x64) . USB driver is DVK 1.1.1.
I think the problem is come from firmware. Does it different between USB 2.0 and USB 3.0?
