i'm trying to integrate Metrologic Fusion MS3780 USB barcode reader to
our system, and trying to make ugen IOCTL reads with USB_DO_REQUEST
since i want the timeouts to work. i can read the data with read() calls 
it blocks.

is there a device does these kind of IOCTL reads so i can setup
up the 'struct usb_ctl_request' correctly ??

// ioctl( fd, USB_DO_REQUEST, ( struct usb_ctl_request *) ...);

i have been getting errno: 22 which is "EINVAL: Invalid Argument"
with my structure setups.

here is the dmesg,
ugen0: Metrologic Metrologic Scanner, rev 1.10/1.00, addr 2

here is the USB info for the device,
