Here is the layout:
PIN1=USB_VCC,
PIN2=D-,
PIN3=D+,

What to do when your computer does not start up normally after installing our USB 2.0 card?

Option#1: Please check your device manager to make sure the driver is installed correctly. If not, remove the driver and reinstall the card by using different PCI slots. Clean the contact of the PCI slot and the gold fingers of the card. Sometimes bad contact can cause the card to malfunction.


Option#2: Upgrade your Windows OS to the latest service pack. You need a full copy of Windows OS to finish the installation, not just a recovery disk provided by your system dealer.


Option#3: Our USB 2.0 cards meet PCI specification 2.2. However, it is not compatible with 3.3 Volt slot.


What kind of OS does it support?
USB 2.0: Our USB2.0 PCMCIA cardbus supports Windows 98SE/ME/2000/XP OS.
FireWire: Our FireWire PCMCIA cardbus supports Windows 98SE/ME/2000/XP OS and Mac OS 9.0 & above. The IEEE1394a controller is compliant to Microsoft OHCI specification so you don't have to install any additional driver, Windows will detect the card and install the OHCI driver automatically. Please make sure you have a full copy of Windows OS, not just a recovery disk provided by system builder.


Do you need a power adaptor?
Generally, the later design of notebook should have enough power to support 2 devices. However, some external devices may need additional power to function properly. Here is the basic specification for the required adaptor.
USB 2.0: T he DC power adaptor is 5V DC. According to USB specification, the USB port can provide 5V at 500mA per port but there is no 5V on the cardbus interface so we need to have a voltage step up circuit to convert 3.3V to a 5V for the USB port. Due to the size of the casing, the step up circuit cannot reach 1000mA so you require a DC power adaptor.
FireWire: The DC power adaptor is 12V DC.


What to do when your notebook does not start up normally after installing our cardbus?
Option#1: Please check your device manager to make sure the driver is installed correctly. Make sure that your notebook can support 32-bit cardbus. To do that, it must be compatible with 3.3V device. Some old 5.0V PCMCIA slot would not be able to handle 32-bit cardbus, and sometimes it will cause malfunction to the notebook.


Option#2: Upgrade your Windows OS to the latest service pack. You need a full copy of Windows OS to finish the installation, not just a recovery disk provided by your system dealer.


Basic trouble shooting tips for USB 2.0 cardbus installation.
a) Listing under "Device Manager" was different from manual.
- Universal Serial Bus Controllers
- Intel(r) 82371AB/EB PCI to USB Universal Host Controller
- NEC PCI to USB Open Host Controller
- NEC PCI to USB Open Host Controller
- USB Root Hub
- USB Root Hub
- USB Root Hub
- Universal Serial Bus Controllers
- NEC PCI to USB Enhanced Host Controller
- USB 2.0 Root Hub Device

Is it correct? Yes, the new orange micro driver is like this. They have split the USB 2.0 and USB 1.1 driver into two parts.

b) After removing our cardbus, the listing under "Device Manager" was back to original.
- Universal Serial Bus Controllers
- Intel(r) 82371AB/EB PCI to USB Universal Host Controller
- USB Root Hub

Is it normal? Yes, the entire NEC driver should be gone!

c) Error occurred while reinserting our cardbus, the listing had a "!".
- Universal Serial Bus Controllers
- Intel(r) 82371AB/EB PCI to USB Universal Host Controller
- NEC PCI to USB Open Host Controller
- NEC PCI to USB Open Host Controller
- USB Root Hub
- USB Root Hub
- USB Root Hub
- Universal Serial Bus Controllers
! NEC PCI to USB Enhanced Host Controller

It did not show "USB 2.0 Root Hub Device". What happened to USB2.0 capability? If you have an exclamation mark next to the NEC PCI to USB Enhanced Host Controller, the driver is not working so the cardbus can run on USB 1.1 mode only.

d) Error occurs while reinstalling driver.
After reinstalling the driver, you got the following error message - "Cannot start this hardware (Code 10)".

It is the same cardbus. The cardbus should be defective. You cannot install the USB 2.0 root hub device if there is a problem with the Enhanced Host Controller driver.

e) System crashed while removing the cardbus.
How to solve it? You need to dismount it from Windows XP before removing the cardbus.
