The mouse works fine under Windows 11 without any issue so far. >Also, can you try getting a trace equivalent to the failure one here, but = with >the standard memset implementation rather than your improved one? I've attached v3 traces from a Kernel with another optimized memset present that works fine with the mouse. I could also try to test the non-working memset with another Sharkoon mouse model attached to the same USB slot. --=20 You may reply to this email to add a comment.
