+This issue is most likely caused by the uftdi module, which has attached itself to the device, whereas openFPGALoader requires it to be accessible as a ugen device.
+
+Unfortunately, due to the security concept of OpenBSD, it is not possible to detach it without modifying the kernel and rebooting the system. However, there are two ways to resolve the issue: Either by patching and recompiling the kernel; or by deactivating the uftdi module.
+
+After COMMENTING OUT the problematic devices in `/usr/src/sys/dev/usb/uftdi.c`, the code would look like this:
+
+.. code:: c
+
+    { USB_VENDOR_FTDI, USB_PRODUCT_FTDI_SEMC_DSS20 },
+    //{ USB_VENDOR_FTDI, USB_PRODUCT_FTDI_SERIAL_2232C },
+    { USB_VENDOR_FTDI, USB_PRODUCT_FTDI_SERIAL_2232L },
+
+Afterwards, the steps in `https://www.openbsd.org/faq/faq5.html <https://www.openbsd.org/faq/faq5.html#Custom>` can be used to recompile the kernel.
+
+Without recompilation, DEACTIVATING the uftdi module can be achieved using the following commands:
