Review on Enhance Your Raspberry Pi Zero Experience with MakerSpot's 4-Port Stackable USB Hub HAT (Camera Connector, Bluetooth & WiFi Supported) by Robert Toomey

I'm editing my old review because I made a mistake. You must ensure the Pi Zero is NOT in OTG mode for this hat to work. If you set it to OTG, the Pi Zero will act as a slave USB hub and the hat will not work. The Pi Zero must be in primary USB hub mode for the hat to function properly. I discovered this the hard way. === Old Review == I recently got this cap and installed it on my Pi Zero W. Long story short, the USB ports on the hat didn't work. Bewildered, I tried two other Pi Zero 1.3, but the USB ports still didn't work. It's installed correctly, so no problem; Power is supplied via the hat's micro USB port. Coincidentally, I found that when I plug something into the USB OTG port, the ports work; They don't work when I plug them into an OTG power port. When I mean everything works, I really mean everything: even plugging in a basic OTG to USB-A adapter (not a device) gets the USB ports working on the hat. I'm really confused. while the product sucks.
