[Libusb-devel] Errors instantiating USB::Busses

[Rick M. <rm...@la...>]

I'm looking into the failures on Mac OS X 10.4.5. The first test to  
fail is descriptor_test. I modified the code a little bit, basically  
moved the first cout statement above the instantiation of USB:Busses,  
and removed everything else. Here's the code:

int main(void)
{
	cout << "bus/device  idVendor/idProduct" << endl;

	USB::Busses buslist;

	return 0;
}


Here's the resulting output, with USB_DEBUG set to 10. Note the Bus  
Error at the end. Any suggestions? TIA!
