Hello,
I have an USB Audio device (win7 x64bit system). It uses system
internal driver (usbaudio.sys) and works well.
Now, I need to add some new functions. I tried to install libusbk
driver and run my new functions program. The new functions work well. But
there is a problem, after I installed libusbk driver, the device will NOT
be an USB Audio device. In order to solve the problem, I have to uninstall
the libusbk driver and install libusbk FILTER driver. At that time, the USB
Audio device works well. However, the new functions program cannot work. I
debugged new functions program and found that *UsbK_IsoWritePipe* failed.
The error code is 1168 (Element not found). Could you give me some
instructions to solve the problems? Thanks.
Best Regards,
Shang Jing
