-device usb-host failing with usbip_vudc-vhdi_hcd gadget
I must admit that I do not know if this is a Qemu or a Kernel issue, but I try reporting here:
When I try to forward a copy of my USB mouse that I made with the new virtual USB device controller in kernel 4.7 I get the following in my log:
[ +0.703256] usb 1-4: reset full-speed USB device number 3 using xhci_hcd
[ +1.020776] usb usb7-port3: Cannot enable. Maybe the USB cable is bad?

[ +0.855005] usb usb7-port3: Cannot enable. Maybe the USB cable is bad?
[ +0.000009] usb usb7-port3: unable to enumerate USB device
the commands I use for makeing the virtual device are(after making a copy of the report description of my real mouse in /root/usb/kingston_report_desc):
mkdir /sys/kernel/config/usb_gadget/winmouse
cd /sys/kernel/config/usb_gadget/winmouse
echo "0x047d" > idVendor
echo "0x1020" > idProduct
mkdir strings/0x409
echo 2016 > strings/0x409/serialnumber
echo Kensington > strings/0x409/manufacturer
echo "Kensington Expert Mouse" > strings/0x409/product
mkdir configs/c.1
mkdir configs/c.1/strings/0x409
mkdir functions/hid.usb2
echo 2 > functions/hid.usb2/protocol
echo 1 > functions/hid.usb2/subclass
echo 4 > functions/hid.usb2/report_length
cat /root/usb/kingston_report_desc > functions/hid.usb2/report_desc
echo 0xa0 > configs/c.1/bmAttributes
echo 100 > configs/c.1/MaxPower
ln -s functions/hid.usb2 configs/c.1
echo usbip-vudc.2 > UDC
usbip attach -r localhost -d usbip-vudc.2
The virtual mouse then shows up as Bus7,Dev10 and I use the option -device usb-host,hostbus=7,hostaddr=10,id=hostdev6,bus=usb.0,port=2 in Qemu to attach it.
This is Qemu 2.7.0 on kernel 4.7.4
Error in title, was supposed to say:
-device usb-host failing with usbip_vudc-vhci_hcd gadget
The QEMU project is currently considering to move its bug tracking to another system. For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or mark it as "Fix Released" if the problem has been solved with a newer version of QEMU already. Thank you and sorry for the inconvenience.
[Expired for QEMU because there has been no activity for 60 days.]
