I have a Dell Inspiron 4100 lap top. This has one usb port which is broken.
There are problems with my mother board I was told so I also can not use a my
pcmcia adapter. I purchased a serial port to usb adapter but it will not
work. The computer shows the device but it's not working. Is there any way I
can get a driver for this device? I have no idea who made this as there is
nothing marked on the device and it came without any info. Thanks.
So to paraphrase your question, you have a USB device, you have a
computer with one working USB port, you connect the device and
something isn't right ?
Start with this program from Microsoft. This is an archived copy.
Click one of the dated links, to download it.

Run the UVCView.x86.exe. Examine the window for USB devices.
Now, plug in the "USB to serial port adapter". Do you see
a new entry appear on the display ? When you click on the
new item, are there gobs of text in the right hand pane
of the display ? Copy that text and post it.
This is a sample screenshot, of what the program output looks like.

The device in that example, has idVendor = 0x0ECD and
idProduct = 0xA100.
I go to this page, and look for that device.

That tells me the plugged in device, was an optical drive
with USB interface.
That scheme is not foolproof, because someone decided
it would be nice if hardware could "lie" about its
identity. So only the most naive devices, look up
easily in the table. For others, you'd still be
completely in the dark, as to what is actually inside
the adapter.
Many types of USB devices, have built-in drivers in Windows.
In which case, no driver needs to be added to the computer.
As an example, USB webcams are split. Some are designed to
work without additional drivers. Others, need additional
drivers to get features not covered in the standard.
So the USB experience will be a mixed bag. Getting some
things to work, is pure misery. If buying USB peripherals,
it is best if they are accompanied by a driver CD, to avoid
going through all of this. Or at least an assurance that
they follow an accepted standard (so you know they'll work
in the OS, without additional software).
