it is the "vertical bar" twice, on my QWERTY keyboard vertical bar is on the backslash key.

i have made a simple hardware interface consisting of an ADC and am trying to connect it to my labtop through usb,,i searched the net and i found that to access usb i need to have a driver for the device and this is done in kernel mode , unfortunately ,i dunt know how to write a driver although am familiar to c++ and vb codes
if any body can help me to write this driver ,, I need it to allow me to send and recieve bits from the ADC (in serial of course)
Maybe what you need is WDK[^]
I think you can also create a virtual COM port "towards" USB devices somehow and then you can reduce the communication with your device to reading/writing the COM port which is probably easier than writing a driver.

i was trying to handle the usb directly through the data+ , data- , Vcc and Gnd pins
i dun know if this is possible ,however, if not , "FT232BL "USB UART (USB to Serial) IC is the only available and i dun know how to configure it even , if u can help me to do so i will appreciate ..
I'm assuming you are not a hard core hardware developer from your question, so I can not recommend http://www.ftdichip.com/[^] highly enough.
Simple electronic interface, and they provide good drivers already - you can just tweak the IDs if you want to make it look like your own device. AND they provide DLLs for interfacing with their device drivers, or you can use them like virtual com ports.
They were helpful when I gave them some semi-daft questions. And they're British!

If your hardware interface has USB calbility, that is for sure it should have some kind of USB control chip. Usually very USB chip has a default USB driver for free. You can add your USB cability basing on your the default driver.
