Final post for me - Done a bit of homework and apparently OTG cable is different from normal USB in that pin 4 and 5 are shorted in the OTG cable. This enables the device to determine which way round it should be going ie whether ir is acting as a host or a slave. All is revealed.

Glad you sorted it - Thanks for the extra info. I did not know that, do now tho'

For anyone who wants to know more you can read at: http://en.wikipedia.org/wiki/USB_On-The-Go

USB OTG defines two roles of devices: OTG A-device and OTG B-device. This terminology defines which side supplies power to the link, and which is initially the host. The OTG A-device is a power supplier, and an OTG B-device is a power consumer. The default link configuration is that A-device act as USB Host and B-device is a USB peripheral. The host and peripheral modes may be exchanged later by using HNP. Because every OTG controller supports both roles, they are often called "Dual-Role" controllers rather than "OTG controllers".

For integrated circuit (IC) designers, an attraction of USB OTG is the ability to get more USB capabilities with fewer gates

According to the very long wiki article it appears the latest trend is auto switching but I can't tell you for certain if that is what the current Excel does.
Somehow I doubt it because of the provision of the longer usb lead for sideloading purposes provided with the Excel.

Maybe someone else has a certain answer?
