Should this issue be closed? --- ** [tickets:#308] ST-link connect issue using latest libusb-1.0.dll** **Status:** new **Milestone:** 0.11.0 **Created:** Fri Jun 11, 2021 10:12 AM UTC by asier70 **Last Updated:** Thu Jun 24, 2021 03:35 AM UTC **Owner:** nobody For years I compile openocd and libusb-1.0 by myself from the newest sources (cross-compilation under ubuntu on Windows 10 for windows 10 x64). I noticed problem with the newest libusb-1.0.dll - I can't connect to st-link (ver. 2.1 and also 3).

Connecting to DAP-Link v2 with bulk works. This issue is for latest libusb-1.0.dll version 1.0.24.11627 (and 1.0.24.11623 as I checked).
