From: Man T on 14 Jun 2010 06:50 XP SP3 My home pc is very slow in copying file from HD to USB port. It took 50 minutest copy a 1.2GB from HD to USB flash key. I thought the problem of my USB key, but it's not. I tried to copy 2.5 GB file in my work pc from USB(my colleague's USB key) to USB(my current USB key), took about 10 minutes. My HD is fast, so should not be the problem. I tried a differenet USB port in my home pc, still very slow. How do I know which USB port is USB 2.0?

How can I tell if I have USB 2.0? http://ask-leo.com/how_can_i_tell_if_i_have_usb_20.html If you are stuck with USB 1 on the m/b you might consider buying a USB 2.0 PCI card, e.g. http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1070706&CatId=511

There are a few motherboards, with a mixture of USB 1.1 and USB 2.0 connectors on them. That happened around the transition from USB 1.1 to USB 2.0. The chipset (Southbridge) may only be USB 1.1, and the manufacturer added a NEC USB2 chip to the motherboard, to run some of the other connectors. In that case, you need to consult the product documentation, to see which connector is wired to which chip. For anything more modern than that, as the ask-leo reference says, finding the word "Enhanced" in the Device Manager, in the USB section, is what you're looking for. it is also possible, to enter the BIOS, and turn off USB2 mode with a BIOS setting. So verifying the USB section in the BIOS, is also part of the checking process. The BIOS setting would control the Southbridge USB port behavior. Once the BIOS setting has been corrected, you go back to Device Manager in Windows, and hope an "Enhanced" entry is waiting for you. There are some more Device Manager pictures here. http://www.usbman.com/Guides/checking_for_usb_2.htm Paul
From: Alan T on 14 Jun 2010 21:29 Thanks, I need to consult my motherboard manual. It's a bit strange as my home system was built 6 months ago, even much newer than my work pc (have been working for more than 1 year). Shouldn't XP SP3 will update/enable all USB 2.0 port automatically? >> If you are stuck with USB 1 on the m/b you might consider buying a USB >> 2.0 PCI card, e.g. >> >> http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1070706&CatId=511 > > The ask-leo reference is mostly right. > > There are a few motherboards, with a mixture of USB 1.1 and USB 2.0 > connectors > on them.

There will be some personal information (like System Name and User Name), and whatever appears to be private information to you, just delete it from the pasted information. Open Device Manager, by clicking Start, Run and in the box enter: %SystemRoot%\system32\devmgmt.msc Click OK. Do you see any red Xs or yellow ?s and if so, in what sections? Now expand the Universal Serial Bus controllers section and look for the words: Enhanced Host Controller Do you see Enhanced Host Controller or not? This will minimize back and forth Q&A and eliminate guesswork. |
