Question about EliteGroup P4M800-M7 Motherboard
My S.O.: Windows XP Professional SP2 PT-BR (Brazilian Portuguese)
My Motherboard: ECS P4M800-M7 (Chipset VIA 8237 - 4USB 1.1 and 4USB 2.0).
When plugin my pendrive Kingston 1g 2.0 in USB 1.1 know sucessful.
But plugin my pendrive in USB 2.0 don't know my device.
All is properly connected. The driver installed is the of the Microsoft Windows XP SP2. Into the site from VIA don't have drivers xp SP2 only to SP1. In some foruns what find the Internet they say what that's a problem of the chipset VIA. Don't know solution. They say too that can be a bug of the driver HUB usb 2.0 and the microsoft sends the patch for email (there isn't link for download). I send a email, but the Microsoft dont answer me.
The USB 1.1 and USB 2.0 is a big issue regarding technology, the 1.1 has maximum speed of 12 megabits where as 2.0 has upto 480 Mbps. And all USB 2.0 devices are compatible with 1.1. Windows XP Home Edition and Windows XP Professional are both fully USB 2.0-compliant with the correct drivers.
So in your case it must work properly. But if the USB 2.0 from microsoft got currepted or badly updated by some thirdparty USB 2.0 driver then it will not work. I have been faced this problem. After doing some stuff I found that if I uninstall the USB drivers and reinstall it from microsoft driver then it works.
So, just go to the Device manager and un-install the USB drivers, then reboot the system to parmanently delete the removed driver. Then install the driver from Windows XP CD.
