i just bought a usb2.0 ext hd maxtor 5000 LE when i have it pluged into my usb 2.0 slot i get random reboots no errors. but if i run it at usb 1 its fine "but very slow"i tried new drivers from maxtor and put in new 4and 1s from via .even went to the extream because of random rebooting i had to reformat.that didnt change a thing.im running xp pro and a asus a7v333 anyone have any ideas on what to try next . thanks

Not sure what to say. I did a Google search for
asus a7v333 USB problem - came up with all kinds of answers/questions. too many to list. You might want to try that.

I have an Asus A7V8X mobo. 4 usb 2.0 ports on the back and 2 that can connect with jumpers to the front panel. The specs say 2 of the back ports are usb 2.0 and the other 2 are usb 1.1. Further the 2 on the mobo that have connectors for jumpers to the front panel are 2.0.

I have a Maxtor 120GB external 2.0 hd. If I connect it to any of the 4 ports on the back AOK. No sweat.

When I connected it to port 5 on the front panel it would restart every few minutes and say fast drive on a slow port. On port 6 it would not restart but would say fast drive on slow port. So, plugged it into the back. No problem.

Later I upgraded the bios and now it works on ports 5 and 6 without protest. No restarting. AOK.

I have another pc with an MSI ultra K-4 board and all the ports work as 2.0 and the external drive works ok.

A third pc is a Dell with P3 cpu. I have a usb 2.0 card in it and it functions fine on both ports with the external drive.

On my laptop--4th pc on the LAN, it simply says fast device on slow port--and that's true....!!!

Be sure and check to make sure Asus hasn't issued a new bios upgrade.

And....if you read the above. Even tho the specs that came with the board said of the 4 back end mounted ports: 2 are usb 2.0 and 2 are 1.1, it seems not to be true.

thanks for the ideas iv tried everything i called maxtor they blame asus so i called them they said update the bios so i did still same thing then after that they said well its a bug with the via chip set and not everybody has these problems they will rma my motherboard if i send it back that sucks .im going to return this hd and get one thats got firewire and usb 2.0 my motherboard has both well thanks again for the help

if its an ASUS board, i presume it has a VIA chipset, because of a "safety" feature if your device pulls more than xxxvolts or mVolts, i forget now. it turns off the port.

The solution is, go into the BIOS and change some settings, if u need them email me or PM me. I had the same problem with my ADSL modem and USB2 HD
