USB 2 Ports Slow
in [Dell]
|
From: Paul on 20 Jan 2010 13:27 The two USB ports have slowed down on my Dimension 3000. When I plug my SD card adaptor in it says that it could perform faster. I have tried uninstalling all the USB drivers in the device manager, and they reinstalled successfully again on a reboot, but with the same problem. What may be causing this?

Which two ports are you talking about? Have you tried one of the ports on the back of the system to see if the problem persists? It is possible that the SmartCard reader is malfunctioning or that it cannot function reliably when connected to the front ports. It is also possible that some of the USB circuitry on the motherboard has failed, but I seriously doubt it. Is there any kind of USB hub in between the card reader and the computer? How long is the cable connecting the card reader to the computer? William

I am starting to suspect the card reader, it calls itself USB2.0 multi reader, and it didn't originally raise the "faster" message on inserting. I have just tried it on a windows 7 and that doesn't give any message, but the transfer rate is slow. Thanks Paul

I think you can rule out the computer itself, especially if your other USB devices work normally. It could be that the card reader has gone bad and won't properly negotiate a USB 2.0 data rate. Or it could be that it never was a USB 2.0 device and is rigged up to somehow report itself as one. William
