Hi,

I'm making a project with USB host midi and I was hoping to encapsulate the host midi functionality within another class, but I have immediately come across a stumbling block...

If I take the InputFunctions.ino for example and I replace these lines

Code:
USBHost myusb;
USBHub hub1(myusb);
USBHub hub2(myusb);
MIDIDevice midi1(myusb);
With a class definition:
Code:
class TestClass
{
public:
  USBHost myusb;
  USBHub hub1(myusb);
  USBHub hub2(myusb);
  MIDIDevice midi1(myusb);
}
I get these errors:

InputFunctions:32: error: 'myusb' is not a type
USBHub hub1(myusb);

^

InputFunctions:33: error: 'myusb' is not a type
USBHub hub2(myusb);

^

InputFunctions:34: error: 'myusb' is not a type
MIDIDevice midi1(myusb);
I have also tried something along the lines of:

Code:
class test
{
public:
  USBHost* myusb;
  MIDIDevice* midi1;

  TestClass()
  {
    myusb = new USBHost;
    midi1 = new MIDIDevice(myusb);
  }
}
and while this compiles, the sketch no longer works.

I'm pretty new to all this stuff and really dont understand what's going on. Any help would be super.
