Today I tried to use the libusb usbdk backend (1.021 release build using
MSYS2 32bit) and it seems to work. You will notice the driver switching
sound when you run openocd.
For the test, I downloaded the OpenOCD 0.10.0-rc1 Windows binary from
Freddie and replace libusb-1.0.dll with the one I built using MSYS2 (with
--enable-usbdk option).
1) Install USBDK
2) Build libusb 1.0.21 release with --enable-usbdk
3) Run cmd.exe as admin and go to USBDK directory
c:\Program Files\UsbDk Runtime Library>UsbDkController.exe -i
Installing UsbDk driver
UsbDk driver installation succeeded
c:\Program Files\UsbDk Runtime Library>UsbDkController.exe -n
Enumerate USB devices
Found 5 USB devices:

USB\VID_0B05&PID_1788 1C4BD6065A96
Descriptor for configuration #0: size 216
4) Now replace libusb-1.0.dll in Freddie's binary with the newly
build libusb-1.0.dll file, I have to copy MSYS2's libgcc_s_dw2-1.dll
as well since MSYS2 is using a different compiler toolchain than
Freddie's cross-compiler.
5) Without changing J-Link's vendor driver (Segger J-Link
driver -- Jlinkx64.sys in my Windows 10 64bit system), you
can run openocd now.
You will notice driver switching during the one (Windows system sound).
