| 1306487 | 2012-10-16 02:04:00 | Why is it that front mounted USB ports are often flaky but rear mounts are pretty much rock-solid. I've noticed that NAVMAN advise using only rear-mounted ports to update their software or when loading maps. Cheers Billy 8-{) |

| 1306488 | 2012-10-16 02:20:00 | Might be this the 2nd to last post (superuser.com) Rear ports come directly from the mainboard - best signal quality, best power quality (through the mainboard layers) Front ports require extra cabling - from the mainboard to the connector in the case. Thus those cabling and additional connectors have impact on the signal quality (480 MBits/s require high frequency!) and power (every cable is like a resistor - some 0.1 Volts will be left on the cable) |

| 1306489 | 2012-10-16 02:20:00 | The rear USB ports are connected directly to the motherboard, where as the front are connected Via wires, the wires can loose / drop a bit of power over their lengths. Not generally enough to worry about, but I have always found if I'm larger transferring files its quicker to use the rear ports, as they transfer faster than the front. Some PC's have USB1.1 ports on the front, other have USB2. I've also found some External 2.5" USB drives dont want to work on the front ports, but work fine on the rear. Plug in a USB Flash drive in the front and they work fine. |

| 1306490 | 2012-10-16 03:56:00 | I found if I plugged my HP Simplesave into a USB hub, it would go deadly slow. When I plugged it into the motherboard it was working at normal speed. | ChazTheGeek (16619) | ||
