Accessing usb flash in qemu virtual machine while runnig windows 8

I run this command in arch linux :

qemu-system-x86_64 -enable-kvm -usbdevice host:4146:3257 -vga std -m 4048 -smp 4 -hda /mnt/win81.img

and this is my lsusb output :

Bus 004 Device 003: ID 4146:3257 USBest Technology

I also create a rule in my /etc/udev/rules.d/flash.rules for permissions .

SUBSYSTEMS=="usb", ATTRS{idVendor}=="4146", ATTRS{idProduct}=="3257", GROUP="users", MODE="0666"

but this error still remains : 

libusb: error [_get_usbfs_fd] libusb couldn't open USB device /dev/bus/usb/004/003: Permission denied
libusb: error [_get_usbfs_fd] libusb requires write access to USB device nodes.
libusb: error [_get_usbfs_fd] libusb couldn't open USB device /dev/bus/usb/004/003: Permission denied
libusb: error [_get_usbfs_fd] libusb requires write access to USB device nodes.
libusb: error [_get_usbfs_fd] libusb couldn't open USB device /dev/bus/usb/004/003: Permission denied

Did you try running it with root permission? I had same issue and doing a sudo worked well for me.
