In my device manager, under USB Contrrollers I only have 3 :

“Intel(r) 82801DB/DBM USB Univeral Host Controller”

but there is no mention anywhere of usb 2.0. I suspect usb 2.0 is not working because am transfering files to my VAIO VGF-AP1 mp3 player, but it takes 10-15 sec per song (which is more like usb 1.0 speed).

I have downloaded the usb 2.0 drivers from the intel website, but they dont seem to fix anything.

Any tips?

Thanks,
Jack

I had raised a similar question myself before as well. Just the interface being USB 2.0 doesnt help. The harddisk drive and the media to which u r copying ur data also need to support such high data transfer rates. I have tried copying data to the sandisk 256 mb USB 2.0 cruzer mini drive but the speeds were just slightly better than 1.0 (or may be the same)...the problem here would be the media used in the cruzer mini drive which just couldnt write data at 60 MBps. I also tried the same with the Sony 80 GB firewire gigavault drive. The supposed speeds are 50 MBps but I got only 10 MBps…dunno whether to blame the TR’s hdd or the giga vault’s media.

it seems u should have another one, the Intel(r) 82801DB/DBM USB 2.0 Enhanced Host Controller - 24CD.  i do.  i also use the adaptec X-hub, which comes with software for viewing ur connections and it even warns u when u have a usb1 device plugged into a usb2 chain.  i like that.

This might seem really simple, but it happened to a friend of mine last month: he was doing a fresh install of XP and hadn’t yet loaded SP1, which contains the support for USB2. So his external HD was really slow until I told him why… Just a detail/reminder…

this *is* a fresh install of windopws xp including the sp1. i take it im gonna have to figure this one out myself…
