[Libusb-devel] Problem with control message

[Linus W. <tr...@df...>]

Thanks for portiong this splendid library to Win32!

Now I have a problem :-)

I claim device, configuration and interface (even altinterface to 0) as
should be done, i.e.

dev = usb_open(device)
usb_set_configuration(dev,1)
usb_claim_interface(dev,0)
usb_set_altinterface(dev,0) (tried to go without this, too)

This works fine. Then the problem occurs in usb_control_msg(): all
messages fail with a -1 return code and the following string from
usb_strerror():

"error sending control message: win error: The I/O operation has been
aborted because of either a thread exit or an application request."

Any ideas of what I might be doing wrong?...

Yours,
Linus Walleij
