Keyspan High Speed USB Serial Adapter ( USA-19HS )

After executing "mknod /dev/ttyUSB0 c 188 0", I am happily communicating with Palms and GPSs using the new /dev/ttyUSB0 device.

Installed the configuration software, plugged it in, and it worked immediately. I am using it with WinXP Service Pack 2, and it communicates great with a complex serial interface to an unusual piece of electronics I have, so its very compatible with "real" serial ports, unlike some other adapters I have tried that seem to only work with modems or PDA docks. The adapter as shipped is actually a small 1"x1.5"x3" box connected to your computer with a 3' USB cable that can be unplugged from it. It has a green LED on top to tell you when it is properly configured as well as when a program has opened that serial port and when it is passing data. Very functional and easy to use; the configuration software even includes tests to make sure the device is recognized and is properly communicating with your computer. The configuration software also ensures that the same COM port is assigned to the device, no matter which USB port on your computer you plug it into each time, unlike previous adapters I've had which created a different COM port each time you plugged the device into a different USB port (very annoying); the driver also has an option to behave like those other drivers, but most people will probably want to always have it act like the same COM port, the default.



Works great with OS X   January 8, 2004

I usually don't write-up reviews, but I am writing this to let those Mac OSX users (inc Panther which is what I am running) know that this adapter does work. I bought this for my Garmin etrex Legend GPS. I use it with my iBook and my Power Mac G4. It was a flawless installation. (1) I installed the Mac OS X drivers (2) told virtual PC to emulate COM 1 using the OS X driver, and (3) Download GPS map data to my GPS. It's that easy! Keyspan has good instructions to set up your serial devices.

I bought this to hook up my Garmin eTrex GPS to my iBook running OS X. It did what it says. I transfer data back and forth without a problem. I use it with National Geographics TOPO map program also available at Amazon.


Connect Garmin eTrex to Mac so you can use TOPOS   June 4, 2005

After trying other USB to Serial Adaptors to get a Garmin eTrex Summit to communicate with an iMac, I am happy to report this one works flawless. (You will need also the Garmin serial connector)

Now you won't have to suffer Windows to use TOPOS with your Garmin.

Want to connect your Garmin eTrex to a Mac so you can use TOPOS, this works, some others don't. (Have not checked this with Tiger, can't think of a reason it would not work)
