Run and Debug Configurations don't work
By script I mean OpenOCD configuration script (debug cfg->debug-> at bottom)
In fact it's not a driver problem since STMLink tool is working properly.
STLink V2 and V2.1 are quite different since USB endpipes seems to be different.
There also seems to be problems with the fact that V2.1 are compound USB devices and that libusb is not so good with those things.
I think the problem is more an OpenOCD problem which has problems with V2.1 devices.
