Thank you for the report.

What do you mean by "partially" here? I'm going to give another look
at that patch soon, will you be available to test my variant if I come
up with one? I have a Launchpad here but not windows 8.1, so can't
fully test it myself.

** [tickets:#96] ti_icdi_usb not choosing the right interface on Windows 8.1**

**Status:** new
**Milestone:** 0.9.0
**Created:** Tue Apr 28, 2015 10:10 PM UTC by Eugene Sh.
**Last Updated:** Tue Apr 28, 2015 10:10 PM UTC
**Owner:** nobody

The Tiva C launchpad with onboard TI ICDI is creating 3 different devices under 
the same VID:PID. Using the `listdevs` example util from libusb-1.0 bundle:

1cbe:00fd (bus 3, device 3) path: 1.1
1cbe:00fd (bus 3, device 3) path: 1.1

And "Stellaris Virtual serial port" in addition. The ti_icdi_usb.c is using the 
"libusb_open_device_with_vid_pid" function to find the FIRST device with the 
given VID:PID and 
attempt to open it, which is failing on Windows 8.1 (it worked on Windows 7). 
It appears that the enumeration order have changed between the win versions. 
[This patch](http://openocd.zylin.com/#/c/2527/) appears to address this issue 
partially.
