Is there a special compile-config option that I have to enable inorder<br>
to get USB 2.0 working? vboxmange list extpacks shows that my extension<br>
pack is installed and usable, and I'm not getting any runtime errors or<br>
even warnings.<br>
<br>
I've been trouble shooting this problem for two days now and I only<br>
managed to isolate the problem to VBoxC.dll. The only way I was able to<br>
get USB 2.0 to work is by replacing my VBoxC.dll with the one packaged<br>
with the virtualbox install.<br>
<br>
Here is my info:<br>
VirtualBox 4.0.4 -- Self Compiled<br>
Windows 7 x64<br>

<br></div>
Early VirtualBox 4.0 source code had a bug where a self-compiled package would not be able to enable USB 2.0.<br>
<br>
I suspect this is what happens here - 4.0.4 is quite old and has this bug. Try 4.0.12.<br>

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

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