I installed (and returned - got a new one) a MSI K8NGM-V with Nvidia
C51G+MCP51G Chipset. I'm running XP Pro, sp2 and a Athlon 3200+
processor.
All 8 USB ports are only running standard - not 2.0. I've run/installed
all
MS and MSI drivers/updates and still can't get any port to run at 2.0.
BIOS is set to USB 2.0 functions (active).
I Have one "enhanced" USB controller adapter listed in Device
Manager (Standard Enhanced PCI to USB Host Controller), but two USB Root
Hubs are not 2.0.
I've tried everything I can think of, including re-installing XP sp2 on
another drive. Same result. Yes, this MB is 2.0 compliant.
Any thoughts?
Pielut:
It's not clear from your query (at least not clear to me) what precisely is
the problem? Is it a question that the system does not recognize a USB
device when connected? Is the problem that (apparently) the USB device(s)
you connect (and what are they?) are operating at USB 1.0 - 1.1 speeds? Are
any messages being generated by the system re this problem? If so, what are
they?
Anyway, be that as it may...
We've put together some "troubleshooting tips" re problems affecting USB
devices in an XP environment. Perhaps it will be of some help to you.
1. Access Disk Management and see if the USB device is listed. If so, and
there's no drive letter assigned, see if you can assign a drive letter to
the device.
2. If the USB device is listed in Disk Management with an assigned drive
letter, right-click on its listing and select Explore from the submenu.
Hopefully, Windows Explorer will open and the device will be listed.
3. Connect the USB device *directly* to a USB port on the computer, not via
a USB hub. Try different USB ports should your computer have multiple ports.
4. Avoid using a USB extension cable.
5. Try connecting a USB device (that does not contain an auxiliary power
supply) to a USB port both before and after the boot operation.
6. Where a USB (or Firewire) external HDD is involved, access Device
Manager, highlight the Disk drives listing and click on the Action menu item
and then the "Scan for hardware changes" sub-menu item. Do the same in Disk
Management > Action > Rescan disks.
7. Try alternate powering on/off methods. If the USB device contains its own
power supply, try booting up with its power on, then try powering on only
*after* the system has booted to a Desktop.
8. Try a different USB cable.
9. In the USB controllers section of Device Manager, uninstall all the USB
controllers listed and reboot.
10. If the device in question is a HDD which you installed in a USB
enclosure, jumper the USB external HDD as Master (or Single if the HDD is a
Western Digital disk). A number of users have reported that jumper
configuration corrected their non-recognition problem. In my own experience
it didn't seem to matter how a USB external HDD was jumpered. But it may be
worth a try.
11. If the device in question is a USB external HDD, first check out the HDD
with the hard drive manufacturer's diagnostic utility. If it checks out OK,
and you can remove the HDD from its enclosure (without voiding any
applicable warranty), do so and install the HDD as an internal HDD to
determine if there are problems with the drive.
12. If the USB device is connected to a USB 2.0 PCI card, try changing the
PCI slot to which it's currently connected to another one.
13. Access the website of the manufacturer of the USB device to determine if
there's any firmware update or info re the problem you're experiencing or
there's any possibility that the USB enclosure itself might be defective.
14. Determine from the manufacturer of your motherboard whether there's a
BIOS upgrade affecting USB device recognition.
P.S.
A number of posters have reported they've found useful information re
troubleshooting USB devices on this site...
