It's coming. Right now the experts are still working on it and they are very close. Right now it's still a little complicated for everybody because you have to alter files and make sure your usb bus is clear of other devices, etc. But be patient it's coming and if you want to go at it anyway then just read all the threads over a couple of times and all of a sudden it begins to make sense and then start just trying different things. All the info you seek is in the threads.
Re: USB conflicts from my experience are avoidable and can be eliminated so you can achieve succes using buster's procedure repeatably. Here is what I have done to avoid conflict in my case.
1. Unplug all usb devices
3. if you get NTLDR error like I do then one of your USB devices (in my case my photoprinter with mass storage device) has become part of your system hardware registry (or something like that) and you need to work around it.
Work around: find out which device is used at boot up as part of your system hardware registry by plugging in devices previously unplugged one at a time and reboot (cntrl-alt-delete). Once you identify that device reboot with only that device plugged in and then unplug usb before OS starts up and identifies/configures the device. This way you get through bootup without configuring device in OS.
4. Now plug in camera to usb
5. Uninstall libusb with cntrl pnl-addremoveprograms
6. Unplug and replug camera
7. Install libusb (note should take at least a minute to identify usb device)Test will show no devices attached
8. Unplug and replug camera libusb test should show camera only attached to usb
9. Run PV2Tool unlock
10. Irfanview to download images as described in busters procedure in success
