Is there a special compile-config option that I have to enable inorder

even warnings.
I've been trouble shooting this problem for two days now and I only
managed to isolate the problem to VBoxC.dll. The only way I was able to
get USB 2.0 to work is by replacing my VBoxC.dll with the one packaged
with the virtualbox install.
Here is my info:
VirtualBox 4.0.4 -- Self Compiled
Windows 7 x64
Early VirtualBox 4.0 source code had a bug where a self-compiled package
would not be able to enable USB 2.0.
I suspect this is what happens here - 4.0.4 is quite old and has this
bug. Try 4.0.12.

Thanks!

No, HGCM is not required for USB2.0.
You get the HGCM error, because the services (SharedFolders,
GuestProperties) were not loaded.
But this does not affect USB 2.0 at all.

Hi all,
Is the HGCM service required in order for USB 2.0 to work?
For some reason USB 2.0 doesn't work with my build and the only
error messages that I see in the machine log is the following:
00:09:31.144 ERROR [COM]: aRC=E_UNEXPECTED (0x8000ffff)
aIID={515e8e8d-f932-4d8e-9f32-__79a52aead882}
aComponent={Console} aText={The service call failed with the
error VERR_HGCM_SERVICE_NOT_FOUND}, preserve=false
Attached is the complete log.
Thanks!
