Hi, platform.io newbie here, trying to upload to my new Portenta H7, using DFU upload protocol. Was wondering if anyone had any ideas as to what my issue could be:
/home/nathan/.platformio/packages/tool-dfuutil/bin/dfu-util: symbol lookup error: /home/nathan/.platformio/packages/tool-dfuutil/bin/dfu-util: undefined symbol: libusb_set_option
*** [upload] Error 127
libusb package issue? I’m not sure where to go with this, any help would be greatly appreciated 
That’s not good – looks like the dfu-util binary dynamically links to a libusb library that is missing a function / symbol.
What does
ldd /home/nathan/.platformio/packages/tool-dfuutil/bin/dfu-util
output?
Hi, thanks for your reply, this is what I get:
| linux-vdso.so.1 (0x00007ffd8b5b7000) | |

Which Linux distribution and version are you using?
HI, I’m on Ubuntu 18.04.6
That’s very outdated.
However, PlatformIO’s tool-dfuutil should locally come with a working libusb-1.0.so.0, to make it work independently of the installed libusb-dev package version of the distribution.
What’s the output of tree /home/nathan/.platformio/packages/tool-dfuutil/?
On a PlatformIO CLI, what’s the output of pio --version and pio platform list?
the tree output is this,
/home/nathan/.platformio/packages/tool-dfuutil/

It indeed seems so that the used dfuutil version in this case does not have a lib/ folder that would have a compatible libusb library.
Try the following:
pio pkg install -g -t "tool-dfuutil@1.9.200310"
cp -r ~/.platformio/packages/tool-dfuutil@1.9.200310/lib ~/.platformio/packages/tool-dfuutil/.
Does uploading work now?
Hi, yep thats done it thanks. was it a version issue?
Yes, without lib/ folder in the tool-dfuutil folder, it would try to use you’re distribution’s libusb-dev package, which seems too old and is missing that libusb_set_option function. Try updating your distribution if you can to avoid future problems with this.
(I’m assuming sudo apt install libusb-dev told you “Newest version already installed”)
ahhh I see thanks for your help!!! Yes it did.
version (2:0.1.12-31)
Yeah that version is from 2017: https://ubuntu.pkgs.org/18.04/ubuntu-main-amd64/libusb-0.1-4_0.1.12-31_amd64.deb.html
On my Ubuntu 22.04 that’s 2:0.1.12-32build3 from 2022: https://ubuntu.pkgs.org/22.04/ubuntu-main-arm64/libusb-dev_0.1.12-32build3_arm64.deb.html
