Hello! You can find the second attempt of my port attached to this email. I have applied the changes, suggested by Stu (Thank you, btw). In this particular port, I have moved the ill-placed troubleshooting guide from the pkg/DESCR into a new pkg/README file. It still includes a section about patching the kernel, since this is the method which is the most precise. Again: The problem it solves is HIGHLY individual, but anybody who will run into it, will be grateful that there is such a relatively easy workaround. In addition to that: Using ldd(1), I noticed that the resulting binaries had some implicit library dependencies. They are now explicitly stated inside the Makefile. Please have another look, hopefully, this time around, it meets your standards a little bit better.

++-------------------------------------------------------------------------------
+
+Note about uftdi(4)
+===================
+
+Up until OpenBSD 7.9, using some FPGA devices with openFPGALoader is sligthly
+problematic, resulting in error messages like this:
+
+ fail to read data usb bulk read failed
+ JTAG init failed with: low level FTDI init failed
+
+This happens because of the FPGA devices being incorrectly attached to the
+uftdi(4) module inside the kernel. There are two ways of preventing this:
+
+ 1. By deactivating uftdi(4) completely
+ 2. By patching uftdi(4), so that it does not recognize the USB device.
+
+In both cases, the ugen(4) module will be attached as a fallback.
+
+Deactivating uftdi(4) with bsd.re-config(5)
+-------------------------------------------
+The following commands
+
+ echo "disable uftdi" >>/etc/bsd.re-config
+ /usr/libexec/reorder_kernel
+ reboot
+
+are disabling the utfi(4) module and relinking the kernel. After the reboot,
+the device can be used.
+
+
+
+Deactivating uftdi(4) with config
+---------------------------------
+The following commands
+
+ config -e -f -o /bsd.nouftdi /bsd
+ ukc> disable uftdi*
+ ukc> quit
+ reboot
+
+Are disabling the module inside the kernel binary.
+
+
+Patching the kernel
+-------------------
+The most precise method is to patch the uftdi(4) module inside the kernel.
+The list of devices uftdi(4) attaches itself to is the array uftdi_devs[] in
+the file /usr/src/sys/dev/usb/uftdi.c.
+
+One single device can be deactived by commenting out the corresponding line:
+
+ { USB_VENDOR_FTDI, USB_PRODUCT_FTDI_SEMC_DSS20 },
+ //{ USB_VENDOR_FTDI, USB_PRODUCT_FTDI_SERIAL_2232C },
+ { USB_VENDOR_FTDI, USB_PRODUCT_FTDI_SERIAL_2232L },
+
+To find said line, the output of lsusb
+
+ Bus 001 Device 006: ID 0403:6010 Future Technology Devices International
+
+can be mapped to the constant defines in /usr/src/sys/dev/usb/usbdevs.h
+Afterwards, the kernel can be rebuild, as described in the OpenBSD FAQ5:
+
+ https://www.openbsd.org/faq/faq5.html#Options
+
+This method is recommend for FPGA projects where an additional USB to UART
+adapter is involved.
+
