My USB devices are getting power when plugged into my ports i.e. iPod is being charged but the devices are not being detected. This is happening on all ports. Devices work properly on other computers.dmafia, As i am currently pursuing a similar problem and being ably assisted by the gurus on this forum you MAY be assisted in solving your problem by referring to the post "Non functioning USB ports" by truenorth. Many of the aspects of my problem will need to be addressed by you to detail exactly what is the state of your USB ports. Good luck,truenorthis this a prebuilt PC or a custom PC?I checked the BIOS and USB was already enabled. The device manager lists 5 USB root hubs and 5 USB controllers corresponding to the 5 ports on the computer. All the devices show up as working properly without conflicts. Again the USB devices i plug in are getting power...an iPod will charge, a flash drive will light up, and the wireless adaptor card light comes on, but they are just not detected by the device manager.
Therefore, it won't connect to the wireless network and the flash drive is useless, etc. It is a Gateway computer prebuilt. It is a relative's computer so just let me know what other information/specs you may need and i'll find out. I know it runs XP. Thanks!One thing you can try...unplug all but the mouse and keyboard.
Travel to Device Manager and right click every instance of USB roots and hubs...make sure to expand the listing to get them all...select "remove" or un-install....you will recieve an error message each time, ignore it.
Power down and wait a few minutes.
Re-boot and let it continue the whole boot process before checking anything. XP will automatically re-install the drivers.
Plug in a USB device after you are sure all activity has stopped and see what happens...Good idea PATIO. That has worked for me in the PAST when i've had hardware issues. Don't know why I didn't think of it in this case. Unfortunately it didn't work. They all reinstalled correctly but that didn't solve the problem. Could it be a driver issue?
thanks truenorth. i've read your thread too...sounds like similar issue although different OS. i may have to bite the bullet and try a clean install....as it isn't my computer tho i'll have to wait TILL they backup all their stuff. it's a Gateway PC, and they called Gateway Tech Support the other day, but no help.If you dont want to do a reinstall you could try cleaning the ports. Some times dirt will make ports unusefull if there not USED and becomed used. If this doesn't work a reinstallment should work like patio said.
