I am hoping that your USb FLASH Drive is a plug and play like a pen drive  so what you can do is   right click on my computer->properties->hardware->device manager the device manager window will open and then you should go to the bottom of the page here you will find a list of USB controllers
what i would recommend is to uninstall all the usb root hubs and any other device you see listed there like usb mass storage etc
also uninstall the controllers if you wish then reboot your computer.
this would solve your problem .
if it does not then there might be a problem with your windows i myself had the same problem with windows sp2 so i upgraded my system to sp3 and reformatted my comp
but try the previous one first  if that solves the problem then you are all ready to go.

Error message usb ports force stopped because of too much power

It will still be covered by the warranty, take it to an apple repair centre, they will have Apple hardware diagnostics software that will be able to determine the cause of the fault. Worst case scenario will be they have to replace the logic board.

If you are using some sort of USB hub the number of devices you are connecting to that single port may be drawing too much power. Try to determine how much power each device is drawing then ask at an apple store how much power the USB port can supply.

USB hub problem.i have a 4-way USB powered hub that has taken it upon itself not to rustle up every now and again on boot-up. Power LED is on but the four green LED's are out and everything connected to it...

Perhaps the problem is not with the powered USB hub but rather the USB port it is plugged into, or the cable connecting them.
Plug the USB hub in using a different USB port on your system or connecting it using a different cable to see if that makes any difference.

My USB port power error message

This happens when anything draws over 500mA, of current, if it was working OK, before, and is working now but displays that message, or not working, well in any case it seems to have gone faulty, and somehow, is now drawing more current drain, the USB port can supply. It may have been spiked too.from all the plug/unplug especially if the safely remove hardware is not used.

I am running Vista and trying to istall easy vhs to dvd into my computor It has accepted all but says usb 2861 device has failed and to check with you to solve this problem Bruce e mail

If you are using more than one USB devices at a time - especially on the same USB physical port (through a hub, say), then there may be insufficient power for the device. If you unplug the device and plug it back in again (preferably on a physical port to itself), if the device is working ok, windows should pick it up and search/ask you for appropriate drivers or manufacturers disk.
Btw give the device at least 10 seconds after unplugging it before plugging it back in again.

USB ports work at 1.1; s/b 2.0

Your computer is functioning correctly.
The USB ports on your laptop are USB1 ports its pard of the hardware.
Your PCMCIA USB 2 card runs at USB 2 speed and therefore when you connect a USB 2 device to this port you will not get this USB message.

Pleasure to see a fellow brown are we related ? :->

have you performed a test of each wire with a multi meter
to determine if each wire is indeed not broken ( open circuit )

if things check out ok with the multi meter , then it's time to start
digging deeper , such as asking yourself if you have indeed ENABLED the usb header at the bios level and has an IRQ that
does not conflict with other devices.

Also you'll want to make sure a driver is properly loaded for each
USB port , sometimes we forget to do all these things.

if all checks out after that , it's time to start getting suspicious
of the device being plugged in to the port , a dirty port can mean loss of connection , silly but so true.

if all checks out after that but still no luck , it's time to start asking yourself if you want to test things farther with extensive
checking of each USB port to make certan each port can read and write , this can be done with certan software.

if everything checks out at that point but still no luck ,
it's time to start asking yourself if you've made a boo boo
by loading an incorrect Operating system, ( rare )

I hope this information has been helpful , sometimes
we fail to get our trouble shooting ducks in a row.

Problem with usb ports

A usb device may have blown out some of the ports, If you have at least one working usb, get a powered usb hub to get more ports.

Check ports are operating correctly, go to Control panel>performance & maintanace>admin tools>services. Look dow list for 'plug and play', make sure this is set at automatic, the furthur down list 'Universal plug & Play' and ensure this is set at Manual. if all is ok then it may be a usb power issue if you ave lots of hungry usb peripherals, try disconnecting some and try your problem periheral in a different usb port.
