| 1295525 | 2012-08-19 16:27:00 | Can someone please enlighten this old fogey about the relevance of USB 1 to 3. Are they a physical item or a software item? How does one increase or decrease the operation and/or system? I have a case fitting that needs replace with only one of my two slots working, but suspect my case is somewhat outdated and may have to be replaced completely. | Sapperbro (6562) | ||
| 1295526 | 2012-08-19 18:25:00 | Usb 1 - 3 are physical hardware ports. 1 being the oldest piece of hardware and 3 being the bewest. Im pretty sure USB 1 is a square connector where as USB 2 and 3 are rectangular. USB 3 is the newly upgradged USB 2 port which has had significant speed and performance upgrades. Be werry though, a USB 3 device costs over double a USB 2 device. | stratex5 (16685) | ||
| 1295527 | 2012-08-19 20:10:00 | USB 1 & 2 are physically Identical and use the same connectors, the only difference is speed. USB 3 is backwards compatible with them and the connector is the same shape but it has extra pins so a USB 3 socket will work fine with USB 1 or 2 devices and vice versa but you will not get USB 3 speeds out of an older port and can not connect a USB 3 port on the motherboard to a USB 2 connector on the case because the motherboard end is different and not compatible. USB 1 - max speed = 12 Mbps USB 2 - max speed = 400Mbps USB 3 - max speed = 5Gbps |

| 1295529 | 2012-08-20 05:37:00 | Thanks all. Given me something to work with. Will a USB 2 pen drive or portable hard drive, work in a USB 1 port. | Sapperbro (6562) | ||
| 1295530 | 2012-08-20 05:41:00 | Thanks all. Given me something to work with. Will a USB 2 pen drive or portable hard drive, work in a USB 1 port. Yes, but very slowly. ;) I've even used my USB 3.0 flash drive in a USB 1.1 port :lol: |

| 1295531 | 2012-08-20 05:46:00 | USB 1.0 - max speed = 1.2 Mbps USB 1.1 - max speed = 12 Mbps USB 2.0 - max speed = 480Mbps USB 3.0 - max speed = 5Gbps Just updated the USB 1.0 / 1.1 / 2.0 speeds there for ya ;) |

| 1295532 | 2012-08-20 20:13:00 | Just updated the USB 1.0 / 1.1 / 2.0 speeds there for ya ;) :p yeah alright. Not so bad just off the top of my head. They are only theoretical speeds anyway and none of them are actually achievable due to overheads etc. |

| 1295533 | 2012-08-21 20:16:00 | To elucidate and get to the nub of my request, I have just resurrected a PIII with a boost in Ram and Hard Drive capacity (second drive for data storage). Running XP. What is required to boost to USB 2? | Sapperbro (6562) | ||
| 1295534 | 2012-08-21 20:58:00 | You can buy a PCI USB2.0 card for around $30 from somewhere like PBTech. | Chilling_Silence (9) | ||
