I have an additional card with USB ports connected to the port on motherboard with flat cable. This card recognises 256 kb flash drive, but on 1Mb card says: "USB device is not recognized". Any ideas?

The message comes up when a USB 2 device is connected to a slower USB 1 or 1.1 port. It is only to advise you that the devise will operate faster on a USB 2 port. If your computer has only USB 1 or 1.1 ports, you will always see the message. You can buy and install a card with USB 2 ports and install it. It will come with the USB 2 drivers. Install the card and the drivers and then connect your USB 2 device to the new hardware and you should not see the message anymore.
Good luck, And let me know ho it works out for you.
it is a hardware conflict, there is no way to fix it, unl;ess perhaps, you had a seperate usb controller for the printer. it is a pci card which you would have to install, and even that is not guaranteed to work.
Hi, For any computer there will be at least 4 usb ports. 2 at the front and other 2 at the back side of cpu. If any one is not recognizing then insert it in different usb port. If any of the port is not working then install the driver for your usb port. Download the usb driver from the below link.
You shouldn't need the USB driver 2.0 from mercury because windows installs this with SP2. Suggest you un-install what you installed from mercury & update your version of windows (completley), through "Windows Update". Once windows is all updated & you have finished with a reboot. Plug your pen drive in a opened usb port. Open windows explorer. Scroll down & you should see an icon (left side of explorer), thats named like, Removable Disk. Give windows time to see the device. After a few minutes if your pen device does not show up try another usb port. One you know does work. If after a couple of minutes go by & you still don't see the device listed in explorer I would say the device is defective. Your Mp4 uses a cable to connect to the usb. Try connecting to another PC's usb port. It is possible the cable is dirty or bad.
The front side port may be a "low power" USB port, it may be possible to "power" this if there is the capacity to connect a power cable to the front panel USB adapter, or there may be an aux power socket to plug into on the motherboard.
yess use the ports in the back of the computer I had the same problem with my mouse before which was also usb port connection. The reason why I say to hook it up to the back usb ports is that it is built onto the motherboard and therefore it would get recognized alot quicker if you put it there if you find that whatever you have hooked up dont have alot of usb ports buy yourself a usb hub i bought one for 2.00 it does the trick when you are limited to usb connections
