how to find out if external HD uses USB 1.x or 2.x?

<< < (2/4) > >>

brotherS:
brotherS, you can easily check what version your USB controller is by doing the following:
1. Call up the Device Manager.
2. Expand the Universal Serial Bus Controllers branch.
3. If it says "Enhanced USB Controller", then your system is USB 2.0. Otherwise, if it says "USB Controller", then the system is USB 1.1.

Thanks, *that* seems to be the problem :-(

how to find out if external HD uses USB 1.x or 2.x?

The text the arrow points to says device isn't working as it should since Windows can't load the needed drivers.

But where do I find the drivers? I just know that it's an ABIT IT7-MAX2 V2.0 mainboard.

mouser:
make sure you dont have usb2 disabled in the bios -- i reset my bios recently and it turned off usb2 support.

wr975:
That's a weird combination. I don't understand why you have INTEL and VIA USB on your board. Did you install a PCI card?

It seems a lot of USB ports are working, so perhaps just try using another port?

About drivers. Win XP SP2 usually needs no drivers for USB but you can still try.

IIRC my BIOS doesn't have such an option.

Hmm, no, but I had to replace my mainboard and the new one came with an extension that gives me a front panel for USB etc. Maybe related?

According to what lanux128 said above they are all working on 1.x only now.

Thanks! On both sides I see several drivers, but nothing that says "USB driver". Does the Intel Chipset Driver take care of USB too? And how can I find out which version of it I installed a while ago?

Btw, I'm using Windows 2000.

f0dder:
Via AND intel usb is a typical mix on a P4 system that has more controllers than the onboard the intel chipset offers - iirc i had a mix like that on my P4 systems.

IMHO a specialized copy program won't do terribly much for speed when simply copying one file at a time - the advantages of things like Overlapping I/O has more to do with application logic and maximal use of threads. And if there's multiple simultaneous I/O, well, disk performance is going to hell anyway :)

I did various tests of file reading methods a while ago, and didn't find any difference in completion speed between Overlapped I/O, normal ReadFile, ReadFile without buffering, and memory mapped files. I did, however, find that memory mapped file access took more CPU time while doing the copy, and that ReadFile without buffering took the least.
