Micro usb hub adapter

Thu Feb 16, 2017 12:55 am

I'm trying to build a retropie setup inside an NES cartridge I bought the adapter listed below on amazon, but the usb data portion didn't work. Has anyone found one that works with the Pi zero by chance? Otherwise all the adapter cables do not fit in the catridge.

The one thing you can do it try giving lsusb command to see any change when you insert this hub. Also check power supply in the USB Hub 4 Pin Connector and see if you see +5V - if you have a multimeter.

Other than that I can not think of anything on the top of my head.

The hub looks the same as the one supplied by WD in one of their kits. That only means the external plastic is the same. The Chinese factories often produce many variations with different silicon inside. You need to know the chip id and that is why you use lsusb.

There is another approach: https://www.adafruit.com/product/3298

The Zero4U stacked on a Pi Zero would probably make it to thick to fit inside a NES cartridge. But one could carefully solder wires from the pogo pins to the matching pads under the Pi Zero.

Another option is a CJMCU-204 4 port hub. According to https://forum.allaboutcircuits.com/thre ... ge.131196/ it's well supported and documented.

OK thanks I'll take a look at those. I was able to get it to fit with a 4 port USB hub from Amazon (3 on the front and one port on the top), but I had to buy a micro USB to USB cable and also had a mini HDMI to HDMI in there so between all of those cables I was unable to put my micro USB male to female sync power cable in there so I just have a micro SD cable plugged directly into the power port of the zero and it just hangs out the bottom of the nintendo cartridge. It's not ideal, but it works for what I need it for.
