I want to thank you [...]. After installing the 2303.pax from iConcepts my OS X 10.4.9 G4 Powerbook fired right up and immediately found my Dynex DX-UBDB9 "USB to Serial adapter" (www.dynexproducts.com) from Best Buy. The device does use the Prolific Technology, Inc. 2303H controller, which is probably why it works so well.

An important note: Dynex links their newest Mac driver on their Web stie, and this device is listed as "Discontinued," so it may be wise to grab their newest driver (PL2303_1.1.0b1.dmg) for your own archive before Prolific drops it.

Here's a link to the new 1.1.0 driver: //www.dynexproducts.com/skins/skin_1/Topics/Drivers/macDriver.rar

Thanks again for supporting the Mac!

Hi Lee

Help. I can't get the darned thing to work. I went to the sakar help site and downloaded the driver there, but it doesn't work. Do you have any advice for a complete computer bone head that is using 10.3.1? I got a killer deal on an old Palm and it is looking less like a deal every minute. Is there another adaptor that works better? I have a few days in which I can return the iconcepts adaptor.

Happy Thanksgiving,

Sumi

I've only used this driver on OSX 10.2.4 (and possibly earlier versions - I don't remember).

Hi Lee:

Thank you for posting information about the latest OS X drivers for the iConcepts USB adapter driver.

Unfortunately, the site you link to does not seem to have the drivers available anymore--either through the browser, or using the terminal.

See the new internal link at the top.

4/30/04 - No more internal link, brand new unified page!

Thanks for getting back to me so quickly!

I'm running system 10.2.8.

I was able to do the commands in Terminal just fine. (Although it took me a while to figure out how to tell it where the file is.. thank goodness for drag-and-drop!) Unfortunately, after restarting, it still isn't working for me.

I still have the receipt for the device (which was recently purchased) and I think I'll just spring for the Keyspan one--at least that company still is in business.

Sorry it didn't seem to work. I've only used this driver on OSX 10.2.4 (and possibly earlier versions - I don't remember).

Lee,

Thanks for keeping this driver alive!

Thought I would let you know about another successful install. Here's my setup:

OSX 10.3 (ie: Panther)

G5

iConcepts USB to Serial adapter

Psion 7

Java-Psion Link 2.0

+reboot

FYI: JPL doesn't like the plain "usb serial" connection, but

/dev/tty.usbserial works fine. Like this:

And Abiword is doing a fine job of editing Psion Word docs. I'm thrilled to have use of my Psion again.

Thanks, thanks, thanks!

-Doug Goodwin

Thanks for your message! It's great to hear that this works with Panther, which I haven't had time to install yet, and that you could use it with the Psion and what I guess is a java program for syncing.

On your webpage [...] the IOGear referred driver page has changed[...]

The link you provided seemed to have dead download links so I stepped back to get new ones. However I am not sure if they truly will drive the IOconcepts device.

I don't have an IOconcepts device but am in the market for a serial to USB converter that is Mac OSX compat, That was how I landed on your page after a quick google search for "USB to Serial Adapter OSX"

Thank you for your research. The new link you found has a download for v. 1.0.8 of the OS X driver, which is a higher version number than any other that I've seen. They say it supports OS X up to 10.3.x, but don't mention 10.4; nevertheless, it seems that this driver is still getting updated now and then.

I've updated this page, incorporating your corrections.

I think if you find one of these devices for sale you would have a good chance of it working with OS X using one of these driver versions, but there's no guarantee. There are other brands as well.

Hello Lee

Your page is no longer available...

[....]

I downloaded the 1.0.6 driver from the link to ram electronics, but got the error from Installer Utility: 'bill of materials could not be found' and 'the archive for this package was not found'

Sorry about that - I don't know what happened to that file! But I put it back, so if you try again you should be able to download. Thanks for the notice.

(Using my wife's account to send this...since it's her Palm!) Anyway, everything went just as you explained with the ibook I just got her. It's annoying to have to reboot to use it (since I don't usually keep a USB cable installed...), but it allowed me to get her addresses for the time being.
