CdcAcmSerialDriver resolves wrong interfaces In/Out #29
Description
I have a CDC device that wasn't working. After some debugging in the CDC driver code, I realised that the IN and OUT interfaces were mixed up. The code assumes the order is always the same.
I rewrote it to be like this;
int numberEndpoints = mDataInterface.EndpointCount;
for(var i=0;i<=numberEndpoints-1;i++)
{
var endpoint = mDataInterface.GetEndpoint(i);
if(endpoint.Type == UsbAddressing.XferBulk
&& endpoint.Direction == UsbAddressing.In)
{
mReadEndpoint = endpoint;
}else if(endpoint.Type == UsbAddressing.XferBulk
&& endpoint.Direction == UsbAddressing.Out)
{
mWriteEndpoint = endpoint;
}
}
so the ordering of the interfaces no longer matters, it should resolve the In and Out interfaces according to their direction.
Hope this helps someone else stuck with this.
