[Libusb-win32-devel] Could not claim interface- requested resource in use.

[Jon B. <Jon...@da...>]

Hello,
 
I am developing my first USB application using libusb-win32.  (Read: I am a
newbie.)  I was getting -22 (EINVAL) returned by usb_claim_interface, until
I read some of the posts and learned that I needed to call
usb_set_configuration first.  Now that I am doing that, I am getting errno
code -5 (EIO), and usb_strerror() returns the following message "could not
claim interface 0, error: The requested resource is in use."   Can anyone
give me any suggestions?
 
Best regards,
Jon
