Re: [libusb] Opening a HID USB composite device using libusb under Linux

[s.rawat <ims...@gm...>]

But my device accepts certain configuration commands on  one instance of
the device and rest on the other instance of the device.I dont know if
"instance is the correct word".
I can do the same(to differentiate) in windows as there is a way to parse
the type of it using hid.dll imported functions.Basically the device
differs in the type of collections - One is Physical and another is
Application - http://www.usb.org/developers/hidpage/HUTRR39b.pdf - Section
1.1  and Section 3.3


reference in Windows :

I want the same to be done using libusb it there a way?


Sorry i forget to post to the libusb group.So sorry for this.!
