ANT Forum

Hi,

I have created a Windows UWP app to run on my Raspberry Pi 2, with ANT USBStick2 attached. Created from the demo app that comes with the SDK.

I am getting "ANTLibrary Exception: Unable to initialize USB....." from the call to device0 = new ANT_Device();

I have trawled through all the previous posts I could find and have tried various things, including the readme.iot file that comes with the ANT SDK for UWP, but still cannot connect to the ANT Stick.

Things I have tried:-

The files ANT.UWPWrappedLib.dll, ANT.UWPWrappedLib.winmd and ANT_NET_UWP.dll are all in the running directory of the app.

I copied the ANT_WinUSB.inf to the Pi and installed and rebooted.

I can see the ANT USBStick2 listed on the "Windows Device Portal" Device Manager with ID: USB\VID_0FCF&PID;_1008\196

When I run "devcon status USB\VID_0FCF"&"PID_1008" on the Pi, I get:
USB\VID_0CFC&PID;_1008\196
Name: ANT USBStick2
Driver is running.
1 matching device(s) found.

On the Raspberry Pi Device info screen, the ANT USBStick2 is listed under Connected devices

I have updated the apps Package.appxmanifest to include the following capability
<DeviceCapability Name="usb">
<Device Id="vidpid:0CFC 1008">
<Function Type="name:vendorSpecific" >
</Device>
</DeviceCapability>

I have also tried using the alternative device0 = new ANT_Device(1, Convert.ToUint32(57600) );

So everything looks good. But I am still getting the exception "ANTLibrary Exception: Unable to initialize USB....." from the call to device0 = new ANT_Device();

I would be grateful for any advice, thanks.
     

Thanks ShaneG for replying.

I have tried both

device0 = new ANT_Device();
and
device0 = new ANT_Device(1, Convert.ToUint32(57600) );

and neither is working for me.

Yes, I followed the instructions in the readme.txt to the letter. Everything on the Pi says that the driver is installed correctly and working.

I even tried to deploy the example demo app and I get the same exceptions from the ANT_Device() calls.

I am thinking that maybe I will purchase the ANTUsb-m and try that, because I have run out of ideas.      

devcon status returns

USB\VID_0FCF&PID;_1008\196
Name: ANT USBStick2
Driver is running.

devcon driverfiles "USB\VID_0FCF&PID;_1008" returns

USB\VID_0FCF&PID;_1008\196
Name: ANT USBStick2
1 matching device(s) found.

So, it seems that the drivers are installed and the device is functioning.      

That's fine, at least I now have an answer to my problem. I had a suspicion that it was the issue.

I will buy a USB-m in the meantime and look forward to the future update.

Thanks for your help.      

The USB-m arrived today. All problems are resolved.
