libusb_set_configuration() and libusb_claim_interface() prepare the raw communication channel.
auth-bypass-tool-v6 combined with libusb provides powerful low‑level USB interaction for security assessments. It effectively bypasses poorly designed hardware tokens that rely on static responses or lack replay protection. However, modern tokens with proper challenge‑response and secure elements are resistant to this approach. Use this technique only in authorized penetration testing or research environments. auth-bypass-tool-v6 libusb
