I could just try this, but I thought I would ask since you guys probably just know.
I was never able to get a USB hub to work and my current layout in the shell probably wouldn't fit one anymore, but I would still like to be able to connect an external controller, a keyboard, or something without having to take the whole thing apart.
If I provide power to a female USB port and connect the green and white wires to pads 22 and 23, will the USB port work even though pads 22 and 23 are also connected to a Teensy? Do I need to get a hub working to be able to do this, or is there another way?
Thanks.

I really don't think this will work. Can you provide more details as to why the hub wont work?jhillman wrote:If I provide power to a female USB port and connect the green and white wires to pads 22 and 23, will the USB port work even though pads 22 and 23 are also connected to a Teensy?

Re: External USB
I have been away from this for a while, so I didn't notice your reply. I'm not sure what to say about why it didn't work. I was following wermy's guide as closely as I could, but when I wired the hub to the Pi, nothing I plugged into the hub was recognized by the Pi. If the hub wasn't connected, keyboards and game controllers were recognized and could be set up. I thought that I might have damaged the hub when I removed some ports so I bought another one and wired it up without modifying it at all (both hubs were identical to the one wermy uses in his guide), but I had the same problem.PotaTox wrote:I really don't think this will work.

My Gameboy Zero is complete and working very well minus the USB hub. I would like to make it work (I would really just like to be able to connect a USB controller, so I don't need the internal port, just one external port), but I'm not sure what else to do. I ended up moving the PowerBoost down to the area where the hub would go to give my self more room for wires, so I'm not sure I have room for a hub anymore.
Thanks.

One, I am going to assume that hubs exist for a reason and you can't connect to devices on one data port.jhillman wrote: I have been away from this for a while, so I didn't notice your reply.

Two, does the hub work when plugged via an OTG cable? Or, maybe even check if the hub works at all by plugging it in to a PC?
Re: External USB
I confirmed with my laptop that all ports worked fine, but I didn't try connecting it with an OTG cable before I wired it to the Pi. That would have been a good idea.PotaTox wrote: Two, does the hub work when plugged via an OTG cable? Or, maybe even check if the hub works at all by plugging it in to a PC?
Re: External USB
I just found out the hard way that one of the usb hubs listed in the wiki does not work on the pi however when I tested it on a pc it worked fine. This is the one that I could not get to work on the pi.
