Re: HidStream.Write throwing Timeout Exception

SO! Just for giggles I tried running this on another computer (just grabbed my laptop and ran out of the build folder)... and it worked. It sent fine.

So, now I guess the debugging comes down to why my workstation cannot send.

Both computers are running Windows 10, where should I even start looking to see why it does not work on my workstation?

Thanks in advance!

HidStream.Write throwing Timeout Exception

I've checked the other threads about this in the discussions, but still have not made any progress on my own project.

I have a CSAFE Fitness device that I am trying to control - the protocol is Master-led and the Slave does not even respond unless it gets a good command. However, I can't even get HIDSharp to even send without throwing a timeout.

Here is my code:

            var usbDeviceList = DeviceList.Local;
            var Concept2Devices = usbDeviceList.GetHidDevices(0x17a4).ToArray();

            HidDevice _c2 = Concept2Devices[0];

            Console.WriteLine("HidDevice:");
            Console.WriteLine(_c2.ToString() + " @ " + _c2.DevicePath);
            Console.WriteLine(_c2.GetFileSystemName());
            Console.WriteLine(_c2.GetFriendlyName());
            Console.WriteLine(_c2.GetHashCode());
            Console.WriteLine(_c2.GetType());
            Console.WriteLine();

            ReportDescriptor reportDescriptor = _c2.GetReportDescriptor();
            DeviceItem deviceItem = reportDescriptor.DeviceItems[0];

            Report ReportTwo = deviceItem.Reports[1];

            Console.WriteLine("Report 0x02:");
            Console.WriteLine(string.Format("{0}: ReportID={1}, Length={2}, Items={3}",
                                ReportTwo.ReportType, ReportTwo.ReportID, ReportTwo.Length, ReportTwo.DataItems.Count));
            Console.WriteLine();

            DataItem ReportTwoData = ReportTwo.DataItems[0];

            Console.WriteLine("Data 0:");
            Console.WriteLine(string.Format("  {0} Elements x {1} Bits, Units: {2}, Expected Usage Type: {3}, Flags: {4}, Usages: {5}",
                ReportTwoData.ElementCount, ReportTwoData.ElementBits, ReportTwoData.Unit.System, ReportTwoData.ExpectedUsageType, ReportTwoData.Flags,
                string.Join(", ", ReportTwoData.Usages.GetAllValues().Select(usage => usage.ToString("X4") + " " + ((Usage)usage).ToString()))));
            Console.WriteLine();
            Console.WriteLine();

            HidStream DeviceStream;
            if (_c2.TryOpen(out DeviceStream)) Console.WriteLine("Connection Open...\n");

            Console.WriteLine("HidStream:");
            Console.WriteLine("CanWrite: {0}", DeviceStream.CanWrite);
            Console.WriteLine("CanRead: {0}", DeviceStream.CanRead);
            Console.WriteLine("CanSeek: {0}", DeviceStream.CanSeek);
            Console.WriteLine("CanTimeout: {0}", DeviceStream.CanTimeout);
            Console.WriteLine("Device: {0}", DeviceStream.Device);
            //Console.WriteLine("Length: {0}", DeviceStream.Length);  //Throws
            //Console.WriteLine("Position: {0}", DeviceStream.Position);  //Throws
            Console.WriteLine("ReadTimeout: {0}", DeviceStream.ReadTimeout);
            Console.WriteLine("Tag: {0}", DeviceStream.Tag);
            Console.WriteLine("WriteTimeout: {0}", DeviceStream.WriteTimeout);
            Console.WriteLine();

            byte[] SetHoriz = new byte[] { 0x21, 0x03, 0x02, 0x00, 0x21 };                       //(CSAFE_SETHORIZONTAL_CMD, 2 x Km units specifier)

            SimpleDumpHex(SetHoriz);

            FormatTX(0x02, SetHoriz, out byte[] TxData);
            SimpleDumpHex(TxData);

            Console.Read();
            DeviceStream.Write(TxData, 0, TxData.Length);  // Timeout Exception

The DeviceStream.Write command times out after 3 seconds.

Here's the output of everything before that:

HidDevice:

21 03 02 00 21

I have some other example code with references to the protocol and communicating with this device, so I know that I need to write to Report 0x02 - but that's about all the information I have.

Is there anything that you could possibly see that I am doing wrong?

I have not even gotten to reading data yet...

Thanks.
