USB 1.0 or 2.0?
Use 'Device Manager' to check your USB devices,
if the word 'Enhanced' is present then you have USB 2.0 JS "John" wrote in message ... How can I determine whether my USB ports are v1.0 or 2.0? -- John |

USB 1.0 or 2.0?
Right click on My computer, left click on Manage, left click on Device
Manager then scroll down to the bottom of the list for Universal Serial Bus controllers. Click on the + to expand the list. If it says "... USB Enhanced Host Controller" anywhere in the list you at least have one USB 2.0 port. If the USB Host Controller is listed without the word Enhanced you have USB 1.1. If both are listed, you have both and it can be a bear to find out which ports are which on a machine. "John" wrote in message ... How can I determine whether my USB ports are v1.0 or 2.0? -- John |

There are some pictures here, of an "Enhanced" entry for USB2. http://www.usbman.com/Guides/checking_for_usb_2.htm Paul "John" wrote in message ...

... How can I determine whether my USB ports are v1.0 or 2.0? -- John Sure fire way is to plug in a USB 2.0 device, XP will spank you (in so many words) if the port is not USB 2.0 capable. This is ASSUMING that you have the USB 2.0 EHCI driver installed and is visible in device manager and shows no problems. -- Dave Speculation on a product or material that is an obvious need, is not speculation per se as there is no risk to the speculator. Common were those selling food and other supplies in the gold rush days. In this case, its oil and its everyone who bites the bullet. And most everyone has no gold to be made, just business as usual. |

"JS" @ wrote in message ... Use 'Device Manager' to check your USB devices, if the word 'Enhanced' is present then you have USB 2.0 That is not necesarily true. Some USB 2 drivers do not include the word 'enhanced' in their name. The best way is to see how many ports you have on the root hubs in device manager. If there are twice as many ports as actual holes in the machine then you have USB2. However, even this isn't foolproof because some machines have ports built into the chipsets that are not brought to the outside world. JS "John" wrote in message ...

USB 1.0 or 2.0?
"John" wrote in message ... How can I determine whether my USB ports are v1.0 or 2.0? You have actually (inadvertently) asked the wrong question. If your PC has any type of USB port then it is USB 2 compliant. USB2 includes USB1.1 as a subset. What you really want to know is if your USB ports support high speed communication. Go to device manager and go to the bottom where the USB devices are. Expand the list and look to see if the word 'enhanced' appears against any of the devices. If it does, you have high speed. If it doesn't, you need to make an additional check. Open the properties of the lowest 'root hub' and select the 'power' tab. If the tab shows the hub as having more than 2 ports then you very probably have high speed ports. If it shows only 2 then you probably don't. The real check is to connect a high speed device and see if you get high speed transfer speeds. |

"John" wrote in message ... How can I determine whether my USB ports are v1.0 or 2.0? The other advice is excellent, but there's another way, too. Do you know what motherboard model is in your system? Or, what's the model of the PC? The system specs will usually give up such secrets. -John O |

Do you know what motherboard model is in your system? Or, what's the model of the PC? The system specs will usually give up such secrets. Unfortunately, even that isn't foolproof. Some PC and motherboard suppliers (and peripheral suppliers come to that) are less than honest and will claim that their product supports USB2 when it does not support high speed communication. They can get away with this because nothing in the USB2 specification makes high speed compulsory. |

USB 1.0 or 2.0?
Hey
what do i do if i have couple 2.0 USB ports...but they act really slow like 1.1 USB ports. the windows update wont let me install the 2.0 drivers and i did what you asked it shows 3 ports available! (this happened when i reformatted my computer a few days ago) yes SP2 is installed already and SP3. when i went to download the enhanced USB driver download, it wont let me install it saying it had some WEB update error or something. please help! you seem to know whats going on ___ "M.I.5¾" wrote: "John" wrote in message ...

(this happened when i reformatted my computer a few days ago) Did you also install the core driver disk that came with your system's motherboard? Do you have such a CD? If not, determine the board make and model (it's screened onto the board itself), go to the manufactuer's site, download and install them. USB ports often won't run as USB2 till those drvers are installed. If your system is more than four or five years old, its ports may, in fact, only be USB 1. (again this will be something you can determine at the manufacturer's site). In that case, you can't change it with software, you have to add hardware. PCI USB2 cards are about $20 or so.
