I purchased the Elonex Artisan media centre case from Ebuyer and installed Mythdora 5 onto it. This is a Linux distribution which consists of Fedora and Mythtv bundled together ready to roll.
I have three Hauppauge Freeview tuners, 750GB drive, 1GB RAM and a P4 3.4GHz processor. All worked fine except for the front panel display.
The following describes how I managed to get the display to work.
To start with we needed to identify the display from all the USB devices. After reading a post on Gmane and looking at Mediaportal I identified the display.
Next, how to drive it.
Looking at the system messages I see this:
Mar 31 15:57:52 mythdora kernel: drivers/hid/usbhid/hid-core.c: timeout initializing reports
Mar 31 15:57:52 mythdora kernel: hiddev97hidraw4: USB HID v1.10 Device [HID 0547:7000] on usb-0000:00:1d.7-4.4

Mar 31 15:57:52 mythdora kernel: input,hidraw6: USB HID v1.10 Device [HID 0547:7000] on usb-0000:00:1d.7-4.4
This tells us that the Kernel has found the display and recognised it as a HID (Human Interface Device) At that point it tries to talk to it and ask it for its HID reports. Unfortunatly the display crashes at this point.
So we need a way to reset the display AND stop the Kernel from trying to talk to it.
Mythtv on the Elonex Artisan

Futaba TSOD-5711BB
This is a 7 segment VFD display with symbols and some buttons. The USB VID:PID is 0547:7000. The display can only show uppercase characters, numbers and a full stop. The symbols consist of a volume bar together with quite a few secret till lit indicators showing such things as REC, CD, TV etc.To start with we needed to identify the display from all the USB devices. After reading a post on Gmane and looking at Mediaportal I identified the display.
Next, how to drive it.
