Thanks Chuck. It is quite possible that I failed to follow the procedure you set about above and that is what triggered the initial problem; bearing in mind that the unit worked initially.
However, I have been much more careful with the new device, unistalling the drivers, reinstalling, re-booting, etc. Yet it still refuses to work in CWBBL. However, it works in Windows Media Player , etc.
Would it be an idea to uninstalled my USB drivers and the re-install? Could it be an Anti virus thing perhaps. Frankly, I'might stunped
