usbip_vhci not loading on Windows 7

[tatokis]

I installed the usbip-win 0.0.4 pre-release on Windows 7 (7601), and even after manually generating a signed cat file, windows refuses to load the driver with Code 39.

Event viewer says

Application popup:  : \SystemRoot\system32\DRIVERS\usbip_vhci.sys cannot find ntoskrnl.exe KeInitializeSpinLock

which looks like Win7 compatibility was broken.

I tried compiling the driver with the old build system and the Win7 DDK but there were quite a few issues and I could not get it to compile successfully.

I do not have access to a proper Windows 10 dev installation at the moment to have a look, so it would be appreciated if this could be fixed.

This issue seems to be duplicate of #8. Anyway, it is almost obvious that usbip-win is not working on win7. But in my opinion, win7 support cannot be a high priority. Win10 is already a major version and there are so many malfunctioning and unstable features even on win10. 😢

Thank you for the response.
I took the time to install VS2017 and the Win 10 WDK.

I changed the project's Target OS Version in VS to Windows 7, and then built the driver.

Windows 7 was then able to successfully load my newly built driver.

I have attached x64 debug binaries built from 94b35a0 for anyone wanting to try to run this.
