usb 2.0 not working, usb 1.1 is! usb 2.0 hard drive, usb 2.0 probl
I have recently installed an external freecom 160gb hdd to my laptop. I am
running XP with sp2. My laptop has 3 usb 2.0 slots of which the enhanced usb drivers are installed. When i plug in my hard disk in get the error message "this usb device can perform faster if you connect it to a hi-speed usb 2.0 port" If you click the baloon it takes you to a screen that showws you a list- which looks like: + SiS PCI to USB Enhanced Host Controller + USB Root Hub (6 ports) Unused Port Unused Port Unused Port Unused Port Unused Port Unused Port AsI said earlier I have 3 physical ports not 6! and they are all saying unused- but the keyboard I am typing this on and the mouse i am using are both plugged in? The device manager shows no problem with any devices! I flattened my PC, and reinstalled everything agin and its still not working! The hard drive works perfectly fine in usb 1.1 though! Note: originally the ports worked fine! Whats the problem? Could it be a hardware fault? someone please help! its driving me nuts! Many thanks for your time Craig

Disconnect the USB mouse/keyboard.
Remove all USB Root Hubs/ports Remove the USB Enhanced Host controller Reboot Access the laptop's BIOS and make sure that USB ports are set to USB 2 and/or Auto. I have seen PCs where you can tell the BIOS which level of USB to use. Restart XP. XP should not re-load the USB controller and USB Root hubs. "cplusher" wrote in message ...

usb 2.0 not working, usb 1.1 is! usb 2.0 hard drive, usb 2.0 p
Hi there
I have exactly the same problem on my HP d530 computer : there are 6 USB ports which should work in USB2.0 But when I plug my external USB 2.0 HDD, it says the same as cplhusher : "this usb device can perform faster if you connect it to a hi-speed usb 2.0 port" And then show me a list with 8 unsed USB 2.0 ports ( I remind that my computer has only 6 physical ports!!) I have tried everything : flash the Bios, update chipset drivers with Intel utility etc... Nothing change!! Can someone help us to solve this???
