Pi zero - micro USB (OTG) hub not working

Tue Dec 29, 2015 6:24 pm

I have a Micro USB OTG hub from Amazon http://www.amazon.com/gp/product/B00FGK ... ge_o09_s00

The hub works fine with all my other OTG devices, but not the Zero... It provides power do connected peripherals, but does not see them, Any suggestions?

Details: I am using the correct port (labeled USB, and not PWR)
I am using Raspbian Jessie
I am using a 16GB Samsung EVO Micro SD Card
The hub, with the exact same peripherals, works on both Android and Windows OTG devices.
I have tested on another PI Zero, with the same results.

Same here. PiZero works with only one of my USB hubs (Fuj;Tech 4-port + Ethernet dongle). The cheap ones from China fail. But the cheap ones work with my laptop.

It is not a power problem. I fed the cheap ones with an external 5V supply to rule out power problems.

I got my Pi Zero up an running with a cheapo China powered one. It's completely unbranded and has four ports, cost about £5 including power supply. I can't even remember where I got it from.

Oh that won't work. It likely will fail because of power requirements.
For example, you plug in a low power wifi adapter in an OTG and then into the pi zero. you boot it up and it works great.
Now you want your wireless keyboard and mouse in there, so you plug all in that OTG hub, you boot it up and it seems to work, then not, then works, then not. Its because of power.

You need a powered hub.

I stick with single wifi directly to the pi zero.

My USB OTG hub comes with a peripheral power supply, and it has a direct Micro USB connector, so it can be plugged directly into the Zero. I can simultaneously run two portable HDD's on any OTG device because it has an external power supply, but the PI Zero is the only one that can't see the hub at all.

I've found that some don't work.. mainly cheap junk from over there.

Try:
* different power supply for pi
* different power supply for hub
* try different hub like the other guy said (about cheap hubs)
* try thicker cables 24Gauge ( cheaper ones use 28 Gauge, note: 1 gauge is a really large piece of copper. 33 Gauge is tiny.)

If all fails then measure the voltage of the power source for the pi and measure the power source for the hub.
Also note the amount of current on the two power supplies - i.e., 1A, 1 Amp, 1000 mA, 1000 miliamps, etc...
So what's a good voltage? Open circuit ( unplugged) and plugged should be 5 volts to 5.25 volts.
How much current? Really, not that much. About 1 A is good for the zero.

Hi guys

Did anyone find an answer to this? I find myself with exactly the same issue.

Ive got that one and it seems to work fine. Havnt tested the sd card and memory card ports tho.
We need to make a pi zero hub blacklist

Thanks for your response, however I was asking if anyone had got these specific USB hubs working before I look to buy yet another hub.

I've been through a few AND with the A+ which has a similar problem. Oddly a plug in keyboard and mouse that often doesn't work yet the WiFi does.

Also found the micro USB port a bit dodgy on the Zero as a Wiggle can disconnect it and that is with the magazine cable too. Shame they didn't use a miniUSB port given they didn't use the microHDMI port used by tablets anyway so size isn't really an issue there.

I had one of those and returned it since I could not get it working on my Zero.

I got one of these and it is working very good:

What chipset does that use.
lsusb should output the info?

I have 2 micro hubs with built in network interface for Pi Zero use. One was fine. The second didn't but I noticed the micro usb plug into the zero seemed a little loose and if I twisted it a bit then the activity light would come on.

Chopped that off and put on a replacement plug and it's been fine since.

The majority of the sub $10.00 USB Hubs use Asix Chipsets, which are supported in Raspbian Jessie.

The ones I've bought of various styles are D-link/?? Chipset, it detect the hub, but on the Zero and A+'s just don't work properly. Plugin keyboards/mice do not work on their own (direct they do) WiFi does even with the keyboards/mice connected or not
They do however work on all the xB's

That is why I ask, you just don't know without buying.
As may be evident from the posts above.

Hmm that's a shame. On the plus side though the £3 Chinese USB OTG Ethernet adapter off ebay works just fine out of the box, so I don't need the hub now. :D

I also got one of those "mini USB LAN 3 usb hub" for a few $3 on eBay, and only the usb hubs worked on my RPi0, but what I needed was the LAN connection. I was able to get my mouse and keyboard to work with the usb hub and into the 3 usb port I connected a wifi dongle. I was able to get wlan working but still not eth0.
You will also need to go to "Raspberry Pi Configuration" and "enable" all of the interfaces, you can disable the camera.
With a connection to internet you need ran the following commands to get the RPi0 eth0 to work:

Code: Select all

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo rpi-update
This will update pretty much everything, including most importantly the RPi firmware.

Except do not follow that advice.
Do not use rpi-update willy nilly, common advice is to use it only if the engineers or support says to OR you actually know what it does, how to recover from it when it goes wrong.
