Have you tried to monitor all requests sent to your driver? You can use the tool KsStudio in the DDK. It might be some property request that is not handled by your driver.

I try to write a simple midi-in driver where data is transfered from a device to some midi software application. Therefore i took the DDK dmusUART sample as a basis and modified it to my needs. Now the driver is just for input. By orienting at the sample and the DDK documentation all pin declarations and property request handlers should be correct. The device shows up correctly in the audio device listings and can be selected as input. But when i try to connect the IMXF is created, initialized and the output connects and immediately disconnects. After that the IMFX is destroyed. This happens about 28 times and no data is transfered. After that the application beliefs it ist connected but the driver shows no singns of life anymore and does not react on any further connection attempts. Can anyone help? Thanks.
