> 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 **Last Updated:** Wed Nov 05, 2025 10:31 AM UTC **Owner:** nobody 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): ~~~ Debug: 111 4 target.c:1598 handle_target_init_command(): Initializing targets...

Everything works fine with these. Any ideas as to what the problem may be here?
