The HID device does not work on Windows #43

Hi,

I connected my device (on which the the demo firmware is flashed), but the device worked only on Linux but not on Windows. I am not sure why. This is the error I get on Windows events log (these messages are copied from different events to give more info):

Device USB\VID_0483&PID_5740&MI_02\7&118ad3aa&0&0002 had a problem starting. Device USB\VID_0483&PID_5740&MI_02\7&118ad3aa&0&0002 was not migrated due to partial or ambiguous match. This device cannot start. (Code 10) Report Descriptor was not byte aligned.

Do you have an idea how to fix it?

Maybe showing my Linux output (which seems to work pretty well) may help? This is how my output in my Linux syslog looks like (the mouse moves circularly as supposed in the demo):

Thanks a lot, this worked perfectly!

If I am not wrong, I do need more than the last commit? because I added the changes on the descriptor from the last commit but that did not work until I took the last 4 commits.
