Hi,

We are developing an HID multitouch device and we want to make it fully 
compatible with Linux and Windows.

The device descriptor describes a mouse, keyboard and multitouch 
digitizer as well as a set of features. When we have mouse or keyboard 
descriptor along the touch device I can no longer get or set features. 
It gives me a timeout error:

ioctl (GFEATURE): Connection timed out

This only happens in Linux.

I would like to know if this is normal, or if there is anyway of getting 
more information about the parsing itself in order to understand the 
problem.

Below is the device report descriptor

__ALIGN_BEGIN
static uint8_t HID_ReportDesc[]
