Re: Trying to get started

Hi Alex,
     Thank you. There must be something missing in setting up the ISO transfer.

Moving the code around I manage to get 400f - transaction not sent on the fram list return - just requesting one frame to start off with.

The same firmware works fine on the PC with Windows or Linux - Will see if anything else comes out of this group.

Hello,

while I am not the USB Team, here is one answer:

The error is kIOReturnNotResponding "Device not responding" as defined in IOReturn.h

Hope that helps a little bit...

Hello USB team,
I have been grappling with the IOKit and been having reasonable success starting developing a device driver for a piece of hardware we have working on Linux and Wintel.

I am specifically having a problem with submitting an async ISO read via

ReadIsochPipeAsync

Does anyone have any pointers to sample code ? Doing a library and web search turns up little.

I am getting a sucessful read request and the callback routine is being activated however I am getting a e00002ed (could not find a cross reference in USB.h) return both on the main return code and the frame descriptor.

Any hints would be gratefully appreciated.

Thanks
