Question about Dell Latitude Cp, Cpi, Cpx, C600, C800, Inspiron 3800 8000 4000 601212 CD-ROM Drive
When I plug my pen drive in the USB port I get the message, "HI-SPEED USB Device Plugged into non-HI-SPEED USB Hub".
I have Windows XP Service Pack2 installed on my Dell Inspiron 8000 laptop.
I know that the transfer from the USB port is slow, and is not at USB 2 speed.
Also, the device manager does not show EHCI installed...
I have not been able to figure out the solution.
Can you help?
You can plug your pen drive backside. if its cant work your computer speed is slow.

Tips for a great answer:
First, please disconnect all USB devices and then perform the following steps:
Click "Start" button, type "devmgmt.msc" (without quotation marks) in the "Search" bar and press "Enter". Click "Continue" if necessary.
In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".
Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".
Then, restart your computer and Windows 7 will reinstall all USB controllers automatically.
click start control panel administrative tools computer management device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X
you will need to update/reinstall drivers
right click to reinstall drivers
if you can see your usb but its not working
ports(com&lpt)right click update driver
sometimes the wires inside the cable will be damaged due to bending or stretching or placing heavy equipment upon the cable
just replace the cable of the hard disk, when you plugged the external disk drive you got that windows could recognize the USB device change the cable everything should work fine again,
if you can see your usb drive but its not working
ports (com&lpt) right click update driver if this fails to fix the problem
check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems to a computer and its parts
