Hi Gerd,
When trying to add a USB device to QEMU (either by command-line or
the Monitor) I'm getting the following error:
"""
husb: open device 1.5
usb_create: no bus specified, using "usb.0" for "USB Host Device"
husb: config #1 need -1
USBDEVFS_DISCONNECT: Invalid argument
"""
I've tried different devices, as I thought this was a problem with
my box, but got the same problem.. Then I debugged and found out that
the problem was introduced by one of the following commits:
"""
commit a5d2f7273c4f59942cc7ffa763d6b60a6f44e908
Author: Gerd Hoffmann <address@hidden>
Date: Mon Aug 31 14:24:00 2009 +0200
qdev/usb: make qemu aware of usb busses.
"""
"""
commit 806b60248218bd5f74a8b070f5a99a864e8e51c6
Author: Gerd Hoffmann <address@hidden>
Date: Mon Aug 31 14:23:59 2009 +0200
qdev/usb: add usb bus support to qdev, convert drivers.
"""
I can't tell which one introduced the problem because with
commit 806b60248218bd5f74a8b070f5a99a864e8e51c6 I get a segfault,
which was fixed by the other.
I couldn't revert them either, because there are rejections,
but resetting the tree right before those makes USB work
for me.
