 Agent forwarding may be chained through multiple hosts. Follow the same [protocol](#remote-host-configuration) to configure each host.
 
+An alternate method is the [usbipd-win](https://github.com/dorssel/usbipd-win) library. If you encounter issues with accessing the YubiKey in WSL after configuring usbipd-win, you may need to add custom polkit rules to ensure proper permissions for the pcscd service. Here's an example configuration using a scard group (the group logic is optional):
+
+Create a new rule file at /etc/polkit-1/rules.d/99-pcscd.rules:
+
+```bash
+polkit.addRule(function(action, subject) {
+    if (action.id == "org.debian.pcsc-lite.access_card" &&
+        subject.isInGroup("scard")) {
+        return polkit.Result.YES;
+    }
+});

 ### Replace agents
 
 To launch `gpg-agent` for use by SSH, use the `gpg-connect-agent /bye` or `gpgconf --launch gpg-agent` commands.
