Hello guys! Thats my first post, please let me know if I did something wrong.
I'm an u7 owner that is facing the same problem as you are.
I've bought a Dell 7567 laptop which have 3 usb3.0 and the u7 is blinking when connected to it. The u7 still works on my desktop on usb2.0.
I have search a lot about that problem and then I remembered I have a usb current meter which I used to measure the current on my phones chargers and cables.
Testing on u7 I've got these currents: desktop usb2.0 = 130mA and laptop usb3.0 = 40mA.
Well, I didn't find anything to change or increase or fix the current on the usb3.0 ports on my laptop. I don't know if its my laptop that is giving less power to the u7 or if the u7 not working well on usb3.0.
Does anyone have any idea if I can increase/change the current on usb port? I'm already using high performance profile for battery and I'm connected to the power. I also disabled the sleepmode for usb on device manager.
Here are the pictures:

Any idea is welcome to try to solve the current problem. I ordered a powered usb hub, probably need wait a month or more to get it... I will try to remember to post back here.
Bye
