The problem I'm running into is that the INF file that libusb created
is apparently "unsigned", where I've never dealt with this problem before.

Here's what happened when I tried to set up LibMTP on Windows 10 just now.

1. I already had the latest libusb device driver binary package installed:
http://sourceforge.net/project/showf...group_id=78138
C:\app\network\libusb\
2. I plugged in my Android device (LG Stylo 3 Plus) and ran
C:\app\network\libusb\bin\inf-wizard.exe.
That asked me to select my device to save the resulting inf file.
NOTE: I hit "install now" but that just gave me the error of:
"System policy has been modified to reject unsigned drivers".
This created a 144-line detailed LG-TP450.INF file.
C:\app\network\libusb\LG-TP450.INF
3. Since I'm 64-bit, I copied these two files
FROM: C:\app\network\libusb\amd64\libusb0.dll
TO: C:\app\network\libusb\libusb0.dll
and
FROM: C:\app\network\libusb\amd64\libusb0.sys
TO: C:\app\network\libusb\libusb0.sys
4. I started the Windows Device Manager (Start Run devmgmt.msc OK)
And I noticed that I had the following entry for my phone.
Portable Devices LG Stylo 3 Plus
5. I selected the Android device from the list and clicked
Action - Update Driver,
I chose "No, not this time" if prompted to connect to Microsoft.
6. I chose "Install from a list or specific location".
7. I chose "Don't search, I will choose the driver to install
8. I clicked the "Have Disk..." button in the bottom right corner
9. I browsed to the .inf file and selected it & pressed OK
C:\app\network\libusb\LG-TP450.INF
10. The name of your Android device appeared in the prompt,
I clicked it and clicked "Next"
(I can't ignore the prompts about Driver Signing,
to continue installation of the selected driver).
It says "Update Drivers - LG Stylo 3 Plus"
"Windows encountered a problem installing the drivers for your device"
"Windows found drivers for your device but encountered an error while attempting to install them."
"LG-TP450"
"The third-party INF does not contain digital signature information"
11. There is no "Finish" buttne; just a "Close" button.

It seems digital signing is preventing C:\app\network\libusb\LG-TP450.INF
from installing properly (which I've never had to overcome before).
