Hello All,
I'm developing a USB Hardware Accessory for Android using the Android USB Accessory API but I'm having a lot of difficulty and wondered is there a specific place where questions would be asked. I'm having problems and have been told that the problems are due to the Android OS and it's not really working as spec'd by Google.

One of the main problems is that Android doesn't send my Application an Accessory Attach event when the USB Accessory device is connected to the Android device. I've had to code to continually poll for a connected device to get around this. My next problem is that the Android does not communicate with the phone reliably. I can connect the Accessory and have the Android send message to the HW device to control it and then I can repeat and have the Android simply not communicate at all with the device. This is not ready for customers at all, unless I'm missing something significant. Given that I've been told these issues are related to the actual OS it seems that there's not a lot that I can do so is the Accessory a Dead End? Is there a team working on this part of the Android OS who I could ask questions of?

The Android I'm using is a Nexus S with 2.3.6 (Not sure that makes a difference as I was told the later versions of the Android Accessory exhibit the same problems)
