From: yang on 21 Mar 2006 23:41 Thank you, I got it. But I have another problem. The PC exchanges information with my hid device by control point(Set Feature and Get Feature), when the app or hid client driver calls set feature to send data to device and calls get feature to recevie the result from device, the function of get feature reutrn error(DATA_ERROR), and wait a moment,call get feature again, it maybe return success or need call get feature once more.So the device is so slowly, and in fact the device had already reday to send data to pc.Why?

sounds like your firmware has issues. this works just fine w/all other HID devices. d -- Please do not send e-mail directly to this alias. this alias is for newsgroup purposes only.
