USB 2/3 query
Is there some easy way to tell if your pc has USB3 ports/capability? I've just gotten three ThinkCenter M91P's (I5's with 8 Gb ram and good size hard disks) on good deal trade. I've found a number of various "manuals" and spec sites that suggest it does have USB3 but they differ on which ports etc. and how many. Too many discordances to pick out the truth. Physically looking at the ports and they all look the same, color etc. Device manager gives no real clue that I can tell. |

[Q67 chipset] * Not a standard feature Additional Information: The Intel Q67 chipset support USB 2.0. Solution The user must install the PCI-E USB 3.0 adapter card to achieve 3.0 speeds. Once the adapter is installed, the user must install the proper operating system drivers === Win7 lacks drivers that can be obtained from the Lenovo support site. TOWER PCI-E USB 3.0 Card, FH FRU 03T7030 Small Form Factor PCI-E USB 3.0 Card, LP FRU 03T7031 " This is why the USB ports in the I/O plate area all have the black plastic in the barrel, as they're USB2. USB3 has its own blue-colored motif :-) In the case of your acquisition, you could check out the slot contents with your eyeball. If a card in the card slot area has the blue tabs, you would suspect someone added the "optional" USB3. When you use add-in cards, the USB3 may not run at full speed. When USB3 ports are on the Southbridge/PCH, then they run at full speed. Or as close to full speed as you're going to get. This shows a design from the same era (P67). Only USB2 show on the chipset. Anything else must be added using a plugin card. http://img.hexus.net/v2/cpu/intel/SB/P67B.jpg Paul |

IME you will usually see "USB 3.0" somewhere in 'Device Manager' under 'Universal Serial Bus controllers' if you have some USB 3.0 ports. The sockets do look slightly different if you look right inside, there are 5 extra contacts in front of the four normal USB 1/2 ones near the tip of the plastic tongue that has the contacts on it. That plastic tongue is almost always blue on USB 3.0 sockets too. -- Brian Gregory (in England). |

"Same color" doesn't tell us WHAT color. https://www.geeksinphoenix.com/blog/...-by-color.aspx Ports *might* adhere to the 'standard' colour coding, but many don't. My (HP) USB 3.0 ones are black and so is the 2.0 one. As Brian Gregory mentioned, if the system has at least one USB 3.0 port, Device Manager should say 'USB 3.0'. As the below Wikipedia picture shows, USB 3.0 ports have 9 pins. USB 2.0 ports have 4 pins. It's not really easy to see the total number of pins, but it's relatively easy to see the number of pins near the outside. If you see 5 pins in a row, it's USB 3.0. If you can't seen a row of 5 pins, but do see a row of 4 pins, it's USB 2.0 (or 1.0). To the OP: On my laptops, the USB 3.0 ports are marked with 'SS' (SuperSpeed) as part of the USB icon. I assume that desktop ports are marked the same. See the top of this picture for an example of the SS+trident icon: https://en.wikipedia.org/wiki/File:USB_3_Pins_static.jpg |
