I am developing an interface to a Topaz signature pad using the SigPlus.Net library.

I’ve used the sigPlus.GetTabletComTest() method to see if the signature pad is connected via USB (found here). The method always returns 0, regardless if the pad is connected by USB or not.

I found another section on the Topaz website that appears to be for VB6 but is something like I’d want to do here. It says there is a method called TabletConnectQuery() that indicates if the tablet is connected. This method does not appear to be valid in SigPlus.Net.

How does one determine whether or not the device is connected to the computer via USB?

Here is the basic code, the sigPlus object is instantiated in InitializeComponent:

public frmSignatureCapture()
{
    InitializeComponent();
    if (sigPlus.GetTabletComTest() == 0)
    {
        MessageBox.Show("No Topaz Signature Device Connected", "Error");
        this.Close();
        return;
    }
}

Topaz tech support confirmed that the TabletConnectQuery() is available on the SigPlus object. The documentation here does not reflect this method though.
