USB device causes PC to freeze. Please help!
Hi
There are two "Enhanced" entries, like you thought. But there is no "USB 2.0 Root hub" only "USB Root hub" devices. The USB device i'm using is under one of those "USB Root hub" when i check the "power" page, next to "general" page. Can i plug USB device to any port, and it will be USB 2.0 compatible? Thanks |

Thanks Yes, I would expect you to get USB2 by using any of the ports. It should be available. There are some much older motherboards, where two chips were used for USB. That meant some ports were USB 1.1 only, while others were USB2. But that was a long time ago. Paul |

"Poppe" wrote in message ... Hi I ran the process explorer. When the freezing occurs, the CPU is 100% idle, and i'm still unable to open windows. Even the Start-menu jams up. Only thing that uses processor while jamming is the process explorer software, and it used it a very little. When i disconnect or remove the USB-dongle, everything works again. It's like putting the PC to deep freeze when using the USB device. If the CPU usage is 100% idle, the freezes must be a hardware issue. It looks like the dongle is locking up the Southbridge USB I/O controller when it's activated, and blocking all other USB devices. That's why the system is not responding to your keyboard or mouse inputs. It's not affecting the CPU operation, or previously running apps, so it's not seizing the total system. It's most likely a driver issue with the dongle. |

The windows i have open at the moment freezing occurs, are usable.
If i have internet explorer open when i input the USB Device, i can use keyboard and mouse normally with it, and open websites. The problem is that i am not able to open any new programs. Even if i try to open the start-menu, it is frozen. Same thing if i try to press ctrl-alt-del, the task manager will not open - until i disconnect or remove the USB 3G Dongle. This is pretty weird. |

There are six USB Universal Host Controller entries (USB 1.1 speed, each controls two ports, for up to 12 USB connectors off the Southbridge).

To find out the number of ports controlled by a logic block, I look that up in a data sheet to be absolutely sure. http://mky.goliath.pseudorational.co...estore/usb.jpg A port can be "bound" to a USB 1.1 or a USB 2.0 logic block, so the choice is either/or for the port when a device is plugged in.

pc freezing
"munyaradzi ngaiso" wrote in message
... what causesthe pc t o freeze if a memory stick is plugged in ? Usually some incompatibility between the stick (hardware) and the XP OS drivers. When we used Win98 we usually had to instal new drivers for each USB device. In theory, WinXP offered standardized USB drivers that would recognize OK every (new, XP-oriented) USB devices, but the this sometimes fails to happen. How old is your memory stick? -- Don Phillipson Carlsbad Springs (Ottawa, Canada) |
