PiZeroW - unable to use as slave USB Device/OTG


Got my Pi0W last week and I’ve been banging my head against a brick wall with this ever since.

I wanted to setup my Pi0W as a slave USB device to emulate WiFi NICs, HID Devices, and Mass Storage - using the gadget modules on the Pi0W is perfect for this. So I followed this guide to get it setup:

but its not worked. The Pi boots ok, but isn’t recognised when I connect it as a USB device to my system.

I’ve tried different cables, different USB ports on my host, confirmed I was using the USB data port on the Pi0W, I’ve reflashed Jessie-Lite twice (jic) but still no luck.

When I connect the Pi0w to a HDMI monitor, power supply and a keyboard, it boots fine and I can connect to my wifi with no issues - ssh is showing as open - so no issue there and I can type normally - it all responds fine and stores any changes I make. Yet whenevr I connect it directly to my host as a USB device - it fails to be detected, mounted or anything else (even when I swap out the modules from G_Ether to G_HID or G_MASS_STORAGE - (and yes I did create a small mass storage block for it to use with the gadget as part of the command line mount).

Do I have a faulty Pi0W or what?



what host system are you using? I haven’t had much luck myself with OTG using my Linux ChromeBook, but my Mac is happy to deal with the same devices that failed there. In other words, it could be the host side not playing ball!


Tried it with both Windows 10 and Debian 9.


I’ve had loads of issues with this as well, I guess some systems just don’t want to play nice with it.

On your Win10 system, does it appear in the networking section of the Device Manager? It should show up as an RNDIS Ethernet Gadget. If there’s an Unknown Device there try unplugging the Zero and see if that disappears, that would suggest it sees the hardware but doesn’t know what it is.


Nope - Nothing gets mounted in Win 10 - no new unknown devices, no new Ethernet NICs, no Mass Storage, no HIDs :(


I’m hardly an expert here, but that would suggest to me that the issue is with the Zero. If the PC doesn’t even show the device it suggests it doesn’t know what it is or it isn’t talking on the USB bus at all.

The cmdline.txt file is apparently very fussy about formatting, did you check that was right? What did you open it with?

Are you sure your microUSB is plugged into the data port and not the power port, and are you sure your USB cable carries data? I have a couple which, for some absurd reason, only carry power.


I edited cmdline.txt with nano - when I hooked the Pi up to a keyboard, power source and HDMI screen to get it onto the WiFi - seemed happy enough. It looks exactly like the example here :

I’ve tested both cables I’ve used with the Pi so far with other USB devices - they’ve been recognised and mounted on both Win and Nix systems with no problems - so neither cable is faulty or power only ones

I’ve also tried both the power and the USB ports on the Pi0W - both let it power on, neither gets it recognised as a device.

I’ve emailed a help ticket into Pimoroni but not had a response yet. Hoping they can help rather than have me go through the faff of returning it for another - as it means I’ll need to get another GPIO hammer too.

I should add - thanks for trying to help though. It’s appreciated.


Continuing to work on this issue. Here’s some of the configs I’ve pulled from the device, and pics of ports in use.

pi@raspberrypi:~ $ cat /boot/config.txt
# For more options and information see
# http://rpf.io/configtxtreadme
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border

# uncomment to force a console size. By default it will be display's size minus
# overscan.

# uncomment if hdmi display is not detected and composite is being output

# uncomment to force a specific HDMI mode (this will force VGA)

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display

# uncomment for composite PAL

#uncomment to overclock the arm. 700 MHz is the default.

# Uncomment some or all of these to enable the optional hardware interfaces

# Uncomment this to enable the lirc-rpi module

# Additional overlays and parameters are documented /boot/overlays/README

# Enable audio (loads snd_bcm2835)

Test with cable 1:

(there is a pic of test with cable 2 but can only upload 1 pic per post apparently).

Connections to raspberrypi.local appear to go via the wifi ipv6 interface, not the USB cable - ping shows this:

At no point do I get the option to install drivers, or even get notified that I have an unknown USB device attached - i.e. I get no recognition that the Pi exists.


Hi, newbie here.

I was just about start a new thread, however noticed you’re having the same issues as me.

In my case I have a Pi Zero with USB Stem and it has been working really well right up until last week. That is it appeared as USB RNDIS Ethernet Gadget in Device manager and I was able to give Usb0 an IP as expected, with no issues.

Now it no longer gets detected by the host, in my case Windows 7 and 10 machines. Device manager doesn’t even acknowledge anything is connected. (Unless I leave the SD card out, in which case it shows up as unknown device - BCM2708 Boot)

I can still SSH using wifi. ifconfig shows usb0, but no IP. Device Manager shows nothing on a couple of machines I have tried.

Nothing has changed that I am aware of.

Anyway, not wanting to hijack your thread, more to highlight that you’re not the only one having issues. Hopefully someone will have an idea how to move forward.

ETA: Just borrowed another Pi0W, connected via USB and using my SD Card, it was detected by the host with no issue. Device manager showed the new device and I was able to SSH raspberrypi.local.

Defective Pi Zero W maybe?
