Hi all,
I'm trying to use a hid device inside qemu/kvm without success.
My host OS is Ubuntu and the guest is a Windows XP.
I have disabled apparmor to have, hopefully, less problems.
Inside the Windows XP "Device Manager" I see the "Human Interface
Device" listed but I'm not really able to use it. I have already seen
this same behaviour when using the device in a vmware virtual machine
where there was no *usb.generic.allowHID = "TRUE"* directive inside
the .vmx file.
Adding that directive I'm now able to use the hid device properly inside
the vmware virtual machines.
When the vmware virtual machine starts I can see in the host, through
dmesg, that the modules usbhid and hid are removed from the kernel.
313 Mar 5 10:37:21 maja-desktop kernel: [ 7878.457020] usbcore:
deregistering interface driver usbhid
314 Mar 5 10:37:21 maja-desktop kernel: [ 7878.457135] usbcore:
deregistering interface driver hiddev
When qemu/kvm starts I see no deregistration messages, therefore I
thought to remove the modules by hand (through rmmod) before starting
qemu/kvm but nothing had changed; The hid device is listed inside the
guest system but I can't use it (I mean I can not receive or send any
message/packet through it).
Running the virtual machine with qemu this is what I got:
sudo qemu -m 512 /var/lib/libvirt/images/builder.img -usb -usbdevice
host:c251:1101
pci_add_option_rom: failed to find romfile "pxe-rtl8139.bin"
usb_create: no bus specified, using "usb.0" for "usb-host"
husb: open device 2.6

husb: grabbed usb device 2.6

I really don't have a clue about what to do...
I'm not sure if it's a kvm or a qemu issue, for sure its really
important to me solve this problem otherwise I can not leave vmware for
kvm.
Thanks all,
Maja
