First I've heard of that. It could very well be Nvidia licensed the |
8 |
VIA IP/logic. |

I'm running a Shuttle SN95G5 box with the nForce3 chipset. |

Did you also select - Enforce USB bandwidth allocation and Dynamic USB minor |
30 |
allocation? Also, Full speed ISO transactions and Root Hub Transaction |
31 |
Translators? The first two were necessary to support my PDA in network |
32 |
mode. The last two I added as they seemed to be good ideas. |

Could be the device itself? I've done a full xfs_dump/xfs_restore via |
45 |
USB on mine to clone my data drive. No problems. |
46 |
|
47 |
The only time I see USB disconnect/reconnet happening is with the KB/mouse, |
48 |
both slow speed devices. I have seen the problem you described on other |
49 |
systems with USB devices that have flakey hubs inside them. |
