Cheap sff usb hub

[AppJunkee]

Hey guys just wanted to share micro center has 4 port usb hubs for $1.43ish and after breaking one open they are the size of about a US quarter coin.
I havent tested it yet but the size works well with the build im doing since i need extra usb ports for the pi zero with using a trimmed down snes pcb for my controls.

Link here: http://www.microcenter.com/product/4661 ... USB_20_Hub

I have these for both my gameboy zero build and my nes controller build and so far both are suffering from the same issue.

1) plug the hub into the pie, everything works like it should, runs two controllers and a keyboard no problem.

2) strip it and wire it up to my pi with the teensy hooked up to port 1. Power the hub and teensy lc from the power strip. Run port two to my full size usb port and power it from the power strip.

3) only detect my teensy lc controller, nothing is detected on my second port (regardless of what is plugged in, and all of the devices worked before).

4) bridge the otg connector (pins 4 and 5). Still won't recognize additional devices.

Lusb shows a 4 port hub connected with only the teensy lc connected.............

Still trying to sort out why it won't work.

After i got home i tested the 3 i bought.

1 works all ports havent broken the case yet.

Second one only 1 port working busted open case has a different board

Third none of the ports work only light turns on busten open different type board of it.

I should also note I forced USB 1.0 and I still have no success. I am fairly new to the programming end of things. Any pointers would be greatly appreciated.

Pics of the hub and the install.

Appjunkee,

Have you had a chance to splice the hub into you SNES controller?

The one I used for NES controller build was tested as you described and worked fine on my test pi (all pors functioned with a keyboard and three gamepads). As soon as I hard wired it to my pi, only one port will work, same as my gameboy zero build. I also tried bridging the otg pins and forcing USB 1 to no avail. Similar error messages to the ones I posted.

I am curious to see if you have the same issue.

Yes i had the same problem from what i read this usb hubs are super sensitive to heat. Im going to buy a few more and see if I find one with all the ports working again. Then I will solder to the wires in stead of the actual board to see if the heat is what fried the chip. I wont have time to go buy more till later this week if not the weekend.

I tried again.

I left my teensy attached to port one as it was working.

I changed from port 2 to port 4 for my sub out connection and now it works ??!!!!!??.

Not gonna worry to much about this, the two ports I need are working now with this very cheap solution.
