Re: [Libusb-win32-devel] Return values

Hi there,
I made some tests using all the endpoints to see what messages I would get
from Debug View logs. Here are the results:
I can only write using endpoint 0x04. If I use endpoint 0x02, the
application freezes. If I use endpoints 0x86 or 0x88, I get invalid endpoint
error (error: _usb_setup_async: invalid endpoint 0x86-0x88).
Writing with endpoint 0x04, I made tests to see where I could read from.
Endpoint 0x88 works fine, but then I get the bandwidth problem. Using
endpoint 0x02, I get the invalid endpoint error (error: _usb_setup_async:
invalid endpoint 0x02). When I try the endpoint 0x86, I get the worst
result: application freezes and I can't even close it using Windows task
manager.
Debug View logs and the application error messages are shown below. Hope
this helps.
