#5720 obsolete Opengl Texturing fails in 3.1.0 cdaragorn
Description

Calling glTexImage2d produces the following errors: OpenGL Warning: vboxCall failed with VBox status code -54 OpenGL Warning: SHCRGL_GUEST_FN_WRITE_READ (28017464) failed with ffffffdb ffffffea

An example of the code I'm using:

      glBindTexture(GL_TEXTURE_2D, mTextures[0]);

      next = VideoLayer::getImage(concat.str().c_str());
      concat.str("");

      if (next == NULL) return false;
      GLint nOfColors = next->format->BytesPerPixel;
      GLenum tFormat;
      if (nOfColors == 4)
      {
         if (next->format->Rmask == 0x000000ff)
            tFormat = GL_RGBA;
         else
            tFormat = GL_BGRA;
      }
      else
      {
         cerr << "image is not truecolor...\n";
         return false;
      }
      glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST_MIPMAP_NEAREST);
      glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST_MIPMAP_NEAREST);
      glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
      glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);

      glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE);

      cerr << "reading texture" << endl;

      glTexImage2D(GL_TEXTURE_2D, 0, nOfColors, next->w, next->h, 0,
        tFormat, GL_UNSIGNED_BYTE, next->pixels);
      cerr << "read" << endl;
      SDL_FreeSurface(next);

      glGenerateMipmapEXT(GL_TEXTURE_2D);

Host System: Windows 7 64-bit Guest System: Ubuntu 9.10 64-bit

This code works perfectly both under the Windows host and under the same Ubuntu guest running Vbox 3.0.12. The program continues to run past these errors, but all textures appear white. All other opengl functions seem to work fine despite the errors with texturing.

#5738 obsolete Error in opening a USB flash drive in "Devices" of Virtual Box guest of Windows Vista host Octavio Tourinho
Description

When trying to open a USB flash drive in the Devices menu item of a VirtualBox guest of a Windows Vista Host one gets the following message:

Error: USB device is busy. Result code: E_INVALIDARG (0x80070057) Component: HostUSBDevice Interface: IHostUSBDevice {173b4b44-d268-4334-a00d-b6521c9a740a} Caller: IConsole {6375231a-c17c-464b-92cb-ae9e128d71c3}

In short, VirtualBox is unable to capture USB device.

I suspect that the reason can be found in item 3.10 of the VirtualBox "Help":

3.10. USB support ... "on windows hosts a kernel mode device driver provides USB proxy support" ...

However, since Windows Vista does NOT allow kernel mode device drivers, I suspect that USB support is being broken by Vista blocking the loading of the driver.
