Devendra, What is the size of the data buffer (in milliseconds) that you are sending to the driver? There is a known problem in the USB driver that restricts the caller to 256 milliseconds of data per request. This will be fixed in upcoming releases.=20 DJ This posting is provided "AS IS" with no warranties, and confers no rights. -----Original Message----- From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of BlazeAudio Developer Sent: Tuesday, March 18, 2003 1:28 PM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] DirectKS and YAMAHA YST-MS35D Has anybody tried to use DirectKS (using the sample or any other way) with YAMAHA YST-MS35D USB device? On a few machines running Windows XP, we get a crash (BugCheck - 0xd1 - IROL_NOT_LESS_OR_EQUAL) as soon as streaming is started. Thanks.
