You mean under Windows? I just did this today, but I'll attach it again.

Can you please run 'xusb -d vid:pid' where vid:pid are the ones of your
device and send the log you get?

Okay, I tested it now at home with Linux and the same usb device. It
seems, that fetching the string descriptor is a Windows problem.
First, I get the error "LIBUSB_ERROR_ACCESS", but then I run the example
with root privilege and everything run fine. Just, for the record: On
Windows I get an LIBUSB_ERROR_NO_MEM error.
What now? My program has to run under windows.
I attach again the descriptor of the usb device, but this time formated
by lsusb.
Best regards

Sorry, this was the wrong attachment.
Here you find the right attachment...
Thanks. So this is a Logitech USB Headset, a USB composite
device with Interface 3 to be the HID interface. Maybe there is
a problem with libusbx HID backend to parse the HID descriptors.
Pete may tell you more about how to debug the issue.
Can you test under Linux to see if xusb works with this device?
If you can please post "lsusb -vvv -d 046D:0A0B" output of the
device under Linux. That should help.
If you can not use Linux, try usbview under Windows first
and post the descriptors.
