Hi all,
am still relativly new to computing, although after a year, and this forums help, i am now a lot more knowledgable. However,,,,, istill cant get my head around a few things, namely usb host controllers etc.
First noticed a problem when i bought an external hard drive for back up of my huge music files. When i copied the files to the external drive, i got a message telling me that , i quote, " a high speed device is connected to a low speed port " then it goes on to say " please enable a high speed host controller ".
Now i figure that if my comouter only supports usb 1.1, then it will just run at 12mbts /sec, whereas a usb 2 would speed things up to 480 /sec. i have bought extra pci usb ports (USB 2 ), and more recently a Belkin usb 2 hub, as i now have an mp3 player and digital camera and need the extra ports. But ,, i still get the same message everytime i connect any of these devices.
Could some one enlighten me a bit more. ??????
Can you actually upgrade the host controller in your pc, to enable the high speed devices to work at high speed ?????? or are we talking about a new motherboard ???
Any advice would be much appreciated.
cheers, kev.

well, a usb 1.1 and usb 2.0 host are completely different....so...if you plug anything usb 2 into a usb 1 port..you'll get that message...even if it's a usb 2 hub...you can get a usb 2 pci card that would giveyou usb 2 support for your faster devices like the camera and your drive...and then use the usb 1 ports for devices that don't matter..

I have already got a pci card, that is supposed to be usb 2, and came with a driver cd. but even plugged into this slot, the message still comes up that no high speed host controller can be found.???

it does seem strange doesnt it. the pci card has 4 usb 2 slots, and 1 firewire, and as i said earlier, the drivers on cd.
So in effect, what you are saying is,,,even a computer that is only equipped with usb 1.1 support , will be able to support usb 2, and transfer at high speed, if you have (like me) a paci card installed ????
Is that right ???
cheers.

right...because that's what the card is for...to interpret the usb traffic and get it to the CPU (which is what a pci bus is for)

You mentioned venturing into the bios ????

If you can give me any advice, on where to look in the bios, and what to when i find what i am looking for it would be great. dont like territory that i am unsure of. Mind you, i am reformatting tonight, and reinstalling a new copy of xp pro, so i dont suppose any balls up would be permenant.
thanks once again.

well...if you mess something up in bios...you can just reset it to the defaults...and...if you want...just go through and look at everything....look for anything mentioning usb or something that looks right....and exit without saving changes then ask in here
