Hi
New member who has been looking round for help for a few weeks, hope you can help me. I've looked around the forum and come across some helpful mails but nothing that has been able to solve my problem.
I have a home built PC around an Asus A8V-VM socket 939 motherboard (VIA VT8251) and Athlon XP64 3700 processor. My problem is that it only detects one device (a multiple card reader) as a USB2 device anything else is detected as USB2, but I get a message saying "this device will work better when connected to a USB2 port" or words to that effect. Windows then shows a list of available USB ports - 7 of the 8 USB2 available are free but I can't seem to find any way of connecting anything to them. Other devices will connect and are listed under different ports, but limited to USB1.1 speeds. Device manager shows one VIA USB enhanced controller and 4 VIA rev5 or later USB Universal Host Controllers. I've tried plugging devices into all available USB connectors - 4 on back panel and 2 on expansion bracket connected to internal MB risers with the same results.
I've installed the latest motherboard drivers I can find and ensured that USB2 options are enabled in the BIOS set up. WIndows USB power management options are disabled.
I'm lost for other possible solutions. At present the card reader is physically connected to the USB expansion bracket having a single USB lead from a 3.5" unit that plugs into a port. This is detected OK as USB2. However the 4 port hub built into my screen which is connected to the other port on this expansion bracket generates the "this USB hub would work faster when connected to a USB2 port" message.
Any suggestions on ways froward before I try to find another motherboard?
