[openocd:tickets] Re: #462 Problems on arm64 host

> How did you route around it if you're talking about the USB hub
integrated on RaspberryPi 5 board? First of all, it's not a full speed
hub there (so the forum thread doesn't apply), second, as seen in
doc/usb_adapters/stlink/0483_3757_stlinkv3pwr.txt it's a high speed
device so no translation is needed in any case. Are you connecting it
via an additional full speed hub?

It's a rPi CM5, with the TI USB hub on the parent PCB.
I understand how that would have been confusing, my apologies.

**[tickets:#462] Problems on arm64 host**

**Status:** new
**Milestone:** 0.12.0
**Created:** Tue Nov 04, 2025 07:00 AM UTC by Mark W

I'm attempting to use openocd to connect to a STLink V3Mods using a Raspberry Pi 5 (arm64) host.

I've built OpenOCD on the host using the cloned master repo from https://github.com/openocd-org/openocd.
As im guessing this could be libusb related, ive tried the os repo version of libusb, and also built libusb from the github master.

The errors i see are (libusb also has debug output enabled):

~~~

I have also tested the exact same stlink and openocd version with a amd64 PC (Debian Linux) host, and Raspberry Pi 3 arm32 (rpi os). Everything works fine with these.

Any ideas as to what the problem may be here?

Thanks in advance.
