Pi Show player USB

[TomP]

Hi all,

I didnt want to clutter the Pi Show player thread with questions so started a new one as I'm having a bit of trouble getting it working.

I've exported a test show that uses both ethernet and USB interfaces and copied it to the Pi.

When I run it i get an error message:
ERROR - Failed to open USB device

The test show still plays with the ethernet controller working fine but the USB controller isnt working.

I thought I may have stuffed up the driver installation so I have reformatted the USB card, a clean install of Raspbian on the Pi and reinstalled everything but with the same result.

Added to rc.local and executed in terminal to test
sudo rmmod ftdi_sio
sudo rmmod usbserial

I then tried building the examples with the FTDI driver installation and executed the EEPROM read example to verify that the driver was working and the USB interface was being recognised which it seems to be as the EEPROM read example returns VendorID and ProductID amongst other data.

Any ideas what I can try please as I am properly stumped

Cheers

Tom
