Actually moving the device to some other port made it work, so then the
suspicious is not the keyboard, but the controller where it's unplugged,
which is the following one:
00:12.0 USB controller: Advanced Micro Devices, Inc. [AMD] FCH USB OHCI
Controller (rev 11).
** Summary changed:
- Usb passthrough on q35 broken.
+ Usb passthrough of devices plugged to AMD FCH USB OHCI Controller failing on
q35.

Title:
Usb passthrough of devices plugged to AMD FCH USB OHCI Controller
failing on q35.
Status in QEMU:
New
Bug description:
I'm trying to setup a q35 vm with windows 7 guest for vga passthrough.
The machine works well for this purpose, but the usb devices passed to
the vm does not. I receive the following errors on screen:
qemu-system-x86_64: libusb_release_interface: -4 [NO_DEVICE]
libusb: error [_open_sysfs_attr} open
/sys/bus/usb/devices/3-5/bConfigurationValue failed ret=-1 errno=2

libusb: error [_open_sysfs_attr} open
/sys/bus/usb/devices/4-1/bConfigurationValue failed ret=-1 errno=2
Disabling IRQ #18
Disabling IRQ #17
And from the system log I can see the following:

I tried to any combination of usb devices, and even disabling the ICH9
usb devices to make the setup looks close to the 440fx machine that is
working for me.
Version of qemu is 2.2.1(all newer versions fails on usb passthrough,
even in 440fx machines), and kernel is 4.1.8.
The script to launch it is the following:
qemu-system-x86_64 -enable-kvm -M q35 -vga none -cpu host -smp
3,cores=3,threads=1 -m 6144 \
-L /usr/x86_64-pc-linux-gnu/usr/share/qemu \
-nodefaults -nodefconfig \
-device ioh3420,multifunction=on,id=pcie \
-device

-device vfio-pci,host=01:00.1,addr=1c.1,bus=pcie \
