BSOD - DRIVER_IRQL_NOT_LESS_OR_EQUAL with usbehci

Ha_Tran · September 23, 2010, 12:09am

Hello,

I’m developing a USB audio device which intends to work with Microsoft WDM audio driver.
On Windows XP and Windows 7, there are no problems, I can play/capture sound through that USB audio device. Windows 2000 SP4 can detect it and load WDM audio driver, but when I try to capture sound from this USB audio device, the computer crashes.

I also use Driver Verifier to have better analysis. Following is the debugged result:

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.
Arguments:
Arg1: b7295020, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, value 0 = read operation, 1 = write operation
Arg4: f66d8c8c, address which referenced memory

Debugging Details:

I can’t find out the reason. I already update the latest version of usbport.sys and usbehci.sys, but the problem still occurs. Do I need to develop a upper filter driver?

Many thanks,

I’m developing a USB audio device which intends to work with Microsoft WDM audio driver.
On Windows XP and Windows 7, there are no problems, I can play/capture sound through that USB audio device. Windows 2000 SP4 can detect it and load WDM audio driver, but when I try to capture sound from this USB audio device, the computer crashes.

Not terribly surprising. Windows 2000 represented the first release of
USB 2.0 and usbaudio.sys in NT. Usbaudio.sys is a complicated
component, and it took a few releases before they ironed most of the
bugs out. You might just have to remove Windows 2000 from your list of
supported operating systems.

What does your endpoint descriptor look like? You might see this if you
tried to do more than one iso packet per frame.

I don’t find tools to get endpoint description on Windows 2000. Can you tell me how to send more than one isochronous packet per frame?

The device is a multifunction one, so if the audio function doesn’t work on Windows 2000, it should not affect others’ operation and should not push the PC to crash. I thought that it could be done by writing a .inf file which would guide Windows to install a “wrong” driver. But it might confuse user with an exclamation mark on Device Manager. Do you know what is a better way to do it?

Thank you very much.

About my endpoint descriptor, on Windows XP, I used the tool UVCView and got the following result:

Both of your Input Terminal descriptors have bNrChannels == 2, but both
of the streaming descriptors show bNrChannels == 1. USBAudio might be
tryinig to figure out what happened to the other channel.

Your setup is a little bit dangerous. You are specifying 8000-M-16
(meaning 16 bits per sample, mono, 8kHz), which has a data rate of 16k
bytes per second. Your isochronous endpoints allow 16 bytes per packet,
one packet per frame, which is exactly 16k bytes per second. That
doesn’t leave any slop for clock skew. If the clocks aren’t exactly
aligned (and they never are), you’ll either run dry, causing a gap, or a
buffer will overflow. You might want to consider increasing the packet
size just a bit to allow some slack.

I don’t find tools to get endpoint description on Windows 2000. Can you tell me how to send more than
one isochronous packet per frame?

You cannot, at least with USBAudio.sys. But then, with your data rate,
you don’t need to. You’re a long way from needing more packets.

The device is a multifunction one, so if the audio function doesn’t work on Windows 2000, it should not affect others’ operation and should not push the PC to crash.

Thank you very much, Tim Roberts.
Your advice of increasing packet size and clock sync really helps me to improve sound quality, especially when the device is doing something else (it’s a multi-function device).

I have configured the stream terminals to be stereo, so bNrChannels = 0x02, but then the sound becomes distorted.

On Windows 2000 SP4, with both packet size increased and stereo stream terminals, the PC still crashes.

Following is the new descriptors, do you see any problems with it?
