3 years ago Hi,
What's dmesg output on rpi?
rpi should be visible in lsusb (keep in mind usb gadget is active only while /dev/iap0 is open)
Some ideas:

3 years ago Thank you for your answer. I've tried many configurations with other gadget drivers and it looks like there is some hardware issue.
Here is my dmesg output:

Check if you have dtoverlay=dwc2 in your /boot/config.txt.

3 years ago @oandrew after testing with different cables and simple g_ether or g_serial gadget drivers, I came to the conclusion there should be some hw issue. I am waiting for new rpi0 and then will update this issue

3 years ago Hi Jean
Did you ever get ipod gadget to work? I'm not getting the device file after loading the kernel modules
[94002.524086] ipod-gadget: init [94002.524088] udc-core: couldn't find an available UDC - added [g_ipod] to list of pending drivers
I'm trying to use it with a AVR-X2300W amp.
Is there some USB/kernel config option I should know about that should probably be mentioned in the readme to enable USB OTG or something? I'm running Ubuntu 20.04 amd64 so its not a DTB issue.
Hi, First, thanks for this nice piece of code.
I could compile, install, insmod g_ipod modules.
/dev/iap0is showing up andipodcommand can connect to it.However, on my linux laptop, I can not see the rpi0 with
lsusb. I have also tried with a Denon AVR-X1200W amp and the rpi0 is not detected,ipodtrace does not show any command.Is it normal
lsusbdoes not show any device with the product_id ? What may be wrong ?My config:
