Nice to see that the new version will have three backend (libusb-win32,
HID and winusb).

I built the new version with MinGW and it seems to run fine. I have two HID
device attached, a PICkit 2 USB programmer from Microchip and a Microsoft
Baisc Optical Mouse. Using the default system HID driver, I can still run the
test program. Can I assume that the HID backend is kind of working now?

PICkit 2 does have two configurations, now it only display the first. Is this
normal?

And if I want to try out a libusb based program ported from Linux, how do I
use the HID backend (without using the device driver)?

By the way, I am using Windows XP SP2.
