So, I am much further along in my build now, and the Arduino works great. I am contemplating just hard wiring to the pins on the back of the port. currently i have a stripped down USB connector that I am using, but it keeps coming unsoldered and makes Arduino a tough fit. I would prefer direct solde...

OK. I think it's all about sharing a common ground. In wermy's guide, he uses two different sets of outputs off of the PowerBoost to power everything. I think for the USB to work, ALL of it has to share the same output out of the PowerBoost. The other output can be used for audio and such, if need b...

I get power to the Arduino, so I don't believe it's a power issue. It's like a circuit isn't being completed. I have been stuck on this piece of it for weeks. After finding a hub that would work, I am now stuck at getting the power draw off of the Pi. I could use a little feedback on my questions ab...

Testing further, if I desolder the power and ground for the hub from the Pi test pads and power them from the PowerBoost, I lose USB functionality. I'm seriously at my wit's end here, guys. I could sure use some help.

I finally found a USB hub that works (one of the octopus style ones from the wiki), but I am noticing something that is different in my build versus wermy's. He wired power and ground for both the external USB port and the microcontroller (Teensy in his case, Arduino in mine) to the PowerBoost and o...

For future reference, make sure to buy one of the "working" hubs from the wiki, as well as short the pins as described in my post above. I got one of the octopus style hubs, and it works.

I think the issue is this: https://www.sudomod.com/forum/viewtopic.php?f=42&t=1345

I tried it, but it didn't work in my case. I think it's the specific hub I'm using.

Sadly, no, and I just posted to your thread on the same subject.

It's almost like it's not completing a circuit. Very strange...

Did you ever figure this out? I have tried 3 hubs and have the same exact issue. With a fourth hub I tried something different. It works fine out of the box if I plug it into my laptop. I de-soldered the 5v and GND in from the input cable. I then hooked soldered the PowerBoost to these two spots on ...
