2444/PCI card/IRQ:9--|
|--(Empty)
Here's the situation. In Device Manager, I have 2 of this controller. One is numbered 2442 & the other 2444. I will identify them by this number for reference. 2442 is an on-board USB, has 2 ports and both of them are at the back (please refer to the diagram above). One is connected to the USB keyboard & the other to the printer, scanner, modem & Zip drive through a USB hub. All this works fine. 2444 is a USB PCI card, also has two ports & they are located at the front (please refer to the diagram above).
I have tried connecting the abovementioned USB peripherals to 2444 but they don't work. I'm assumming that there is something wrong with the ports &/or the card altogether as the USB peripheral are found to be working and the controller is detected in Windows XP.
Do note that 2444 also has two 1394 port at the back & one in front. I hope my explanation is clear & if more information is needed to help, please ask. Any/all help is greatly appreciated.
Thank You
