Hi,
http://leaf.dragonflybsd.org/mailarchive/kernel/2007-11/msg00034.html
This should be easily reproducable using qemu with -usb and -usbdevice options.
Regards,
Michael

USB patches
| From: | Michael Neumann <mneumann@xxxxxxxx> |
| Date: | Mon, 19 May 2008 12:58:39 +0200 |
Hi,
A patch (usb.diff) that brings in all recent FreeBSD-current USB changes (no devices yet). Tested on two laptops and qemu. All three paniced before with the same message as in this thread:
http://leaf.dragonflybsd.org/mailarchive/kernel/2007-11/msg00034.html
This should be easily reproducable using qemu with -usb and -usbdevice options.
After the patches, all three boot up and I can use USB without problems. One problem is not yet fixed: When I boot with a USB device connected, it sometimes hangs.
The second diff (freebsd.usb.diff) is against FreeBSD-current as of yesterday.
Regards,
Michael
