Basically I'm developing USB device, which will be using MTP for file transmission. It works fine with Konqueror, and Dolphin I can successfully copy files around, also mtp-getfile works (on Linux).

On windows I can see my device and list files, but when I try to copy any of them, I'm getting "Catastrophic error":

.

I'm logging all requests from computer to device (operation codes and params) and there is no pending operations during error, so I'm guessing that it's caused by something earlier (like missing support for something which should be presented in DeviceInfo response).

I tried looking in Event Viewer, but there is no sign of that failure, also details of device in device manager looks correct. Here is dump from mtp-detect fired on linux:

libmtp version: 1.1.16
