Actually what we are seeing is that the HCT 11.0 test is sending our driver IRPs(like IRP_MJ_READ) for major functions that we have not substituted a dispatch routine for. Can anyone explain why this would be the case. Our driver is a miniport audio adapter driver. Thanks for any help! -Val 0x0 wrote: From: "Val Camacho" To: Sent: Tuesday, September 17, 2002 1:08 PM Subject: [wdmaudiodev] HCT 11.0 - Help > > Hello All: > > We are having some problems running HCT 11.0 on WinXP SP1. A driver which passes HCT 10 is failing HCT 11.0. I am new to this and was wondering if there is any documentation which describes in detail what the HCT 11.0 tests are doing. Thanks for any help! > > Val [snip] Hi. I too pass HCT 10.0, but with HCT 11.0 portcls.sys crashes for me in the driver verifier test (winxp sp1 of course). I gave a stack trace in my very recent posting. Are you getting the same symptoms? For documentation, HCT docs and a debugger (and this list) are your only source of what is happening, as far as I am aware. pagefault0xe ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.de/ --------------------------------- Do you Yahoo!?
