My (no-name) USB GPS receiver arrived without software. Help.

HI All,
I have a usb gps receiver that I got on e-bay but it arrived with no software and no brand name anywhere. I'm trying to run microsoft streets and trips on an old laptop ( passed down from college daughters) in my service truck.
I plug it in but nothing happens, when I open streets and trips and try to configure the gps, it's like it's not even there...
Thanks in advance..

When you plug it in, Windows should know it's there even if it doesn't know what drivers it needs. It may be defective.

I've never seen a GPS antenna (I assume that's what you meant) without some kind of name on it. If you could upload a picture, someone might recognize the shape.

Youl could go to the below-listed link and look around. It's GPS-related downloads from Downloads.com, aka CNet.

Pictures are a good idea...I've posted 2 in my album

Thanks

If, when you plug it in Windows does not ask for a driver;

1.) you have already installed the driver or
2.) you have told it not to look or
3.) the device is faulty.

In any case, go to Device Manager (I will assume XP, if Win98 all bets are off). From Control Panel, choose Performance and Maintenance. Click 'See Basic Information...' to bring up the System Properties box. Choose the Hardware tab and Device Manager button.

Plug in the GPS device.
If you see a yellow question mark, Windows does not recognize the device as in 2 above. You can right click on it and uninstall it.
If not, click on the + sign next to Ports to expand it. Look for a GPS listing and note the COM port number. That is the one you would use in S&T.
Otherwise your device is faulty.

Thanks for the help, looks like I got 'junk' on ebay. It says the usb port has a power surge and shuts down when it's plugged in.....

Mike, search for BU-353. That's a popular USB GPS receiver. Many many paople use it. It performs very well.

You need USB to serial driver.

Some of the older laptops have defective USB implementations and can't supply enough power to the USB buss ... This also happens as laptops get older and the electrolytic capacitors in the switchmode power circuits dry up. I have an old Compaq 550Mhz PIII where my GPS works fine but my USB Edge modem has to be plugged in before I boot the computer or it will shut down power to the USB port. Made it a real nightmare getting the drivers installed because you are supposed to install the drivers and hotplug the modem but when you hotplug the modem the USB power would shut off. Since it had only one USB port that meant to switch from GPS to Edge modem I'd have to shut down the computer every time. Finally it got to the point where the Edge modem would shut down the power to the USB port no matter what

I'm sure new it would have worked fine but as the power circuits and electrolytic caps aged it got weaker and weaker. Too bad because it was an aluminum cased business computer (Supposedly the 1st laptop capable of DVD playback) and was rugged. Now it's been relegated to my electronics bench for use with my PC digital storage O-scope and spectrum analyzer which is parallel port based and works like a champ.

I'd try it on a newer computer before I blamed the GPS unit itself because it's likely the problem is a weak power supply for the USB port on your computer

It will not even work on a new PC without a USB to serial driver.

They didn't get far enough to see if it was a USB-serial driver problem. It reset the USB power when connected pointing to either a faulty GPS device or weak laptop supply (as longjohn119 was suggesting).

I'm bettin' it's a faulty receiver. This is probably a good time to say it's advisable to buy the best you can afford. A lot of us are on fixed incomes and some of the high-dollar stuff doesn't come easy but being "penny wise and pound foolish" can come back to haunt you. I bought an extended power battery for my cell phone on eBay. It cost 18.00. My cell phone company (I won't name them) wanted $40+ for the exact same thing.

I happen to use DeLorme's receiver for SA and MS's receiver for S&T. The S&T receiver is a Pharos.

Shop around on eBay and at the dedicated GPS sites and you can find some real bargains on some premium merchandise. But remember, when you shop online, shop carefully.

Are you saying you installed the correct USB to serial driver and it still doesn't work?

Who are "they"?
