Subject: [Qemu-devel] need help getting a USB audio device to work
Date: Sun, 03 Jan 2010 11:19:01 -0700 [thread overview]
Message-ID: <4B40DF95.5060702@cisco.com> (raw)
After weeks of fruitless effort I could use some help getting a USB
audio device to work. I have instrumented the hell out of the guest
driver and uhci code, qemu's linux and uhci code, and the host side usb
code. Near as I can tell data from the device makes its way into qemu
(async_complete shows a urb length equal to the data the host OS
receives from the device), but the data does not appear to make its way
to the guest OS. I have tried a variety of guests -- Fedora 12, RHEL5.3,
and RHEL3U8, and none work.
How do I determine in fact the data pulled into qemu from
ioctl(USBDEVFS_REAPURBNDELAY) is getting pushed to the guest?
Thanks,
