[Lcdproc] Unknown VFD display

Hi all,

I have a PC with the next VFD and it's USB-based:
TOR9326 VFD 020V2
C95242-104
Tatung

mythtv:~# lsusb
Bus 004 Device 002: ID 8086:6772 Intel Corp.

In windows it's installed as a HID device.

According to the documentation of lcdproc, most USB displays use the
device /dev/ttyUSB*.
But I don't have such a device. Is it the kernel that's responsible
for creating this device or is it one of the lcdproc drivers? I assume
that I have to see the device in dmesg before I can start using
lcdproc?

What is the best way to accomplish this? Do I have to hack the kernel
code or do I have to add it to /var/lib/usbutils/usb.ids?

Any help would be appreciated to get me started.

Thanks,

Wouter
