What else do you have on the USB bus? |

AIUI the Playstation "Eye" camera is pretty good quality - certainly |
21 |
looks that way to me - and is known for pretty much maxing out the bus |
22 |
it's on. I believe it will suffer if it's plugged into a USB hub, or |
23 |
if anything else is plugged into the same USB bus - AIUI this may even |
24 |
include the adjacent USB port on the back of the PC. |

That camera appears to be about the same sort of resolution as the one |
27 |
you're talking about, so you may find the same issues affect you: |

You also need to be sure your USB ports are of the current generation, |
31 |
and not the older slower type. |

It is rather a shame that firewire was less successful - I appreciate |
34 |
the cheapness & ubiquity of USB, but AIUI firewire does not suffer |
35 |
from quite the same bandwidth issues. |

You can pick up these Playstation "Eye" cameras for about £20 or £25, |
38 |
although you may find the angle of view a little wide for birdwatching. |
