Thanks for the info PotaTox. I went from a broken USB hub to a perfect one.

Soldering PP40 to PP35 will result in canceling the OTG, and will give you the change to use any USB Hub. PP40 is the crossover pad from the backside of the microusb connector's OTG pin. PP35 is GND. I have been using this for a while now in my Zero builds.

I am not sure if it works for the Zero W, I have to look in to that, but it works for the Zero 1.3.

Edit* Looks like should work for the Zero W. Al though the pads are no longer numbered it should be the same pads as before.

Well thanks for the help but didn't work for me xd my hub only "catches" one signal. I have it well wired but the might be some reason. I have PP22 and PP23 in the input hub and supplying by the powerboost, then I got the teensy and keyboard. It detects the teensy but if I disconnect it then detects the keyboard. I will configure GPIO as inputs instead :)

I found a solution. PP22 and 23 wired to the hub didn't work, even with PP35 and 40 wired, so I insert a microusb-otg and wire only the data wires to the hub. Now it detects teensy and keyboard, but I problem arrived: I can't have one microusb cable in the case, its too big, and I think if I wire to that pins ( insted of insert it) will not work

Fixed: Instead of solder pp35 and 40, I had to solder the ID pin of the microusb socket directlt to ground, now it works perfectly :D :D
