Snow Leopard USB?

[vinny2cubes]

I just installed SL on my MacBook pro and now I don't see a usb port in the preferences/devices pane. The only options I have are for bluetooth-pda sync and bluetooth-modem. Got any ideas?

Forgot to add that I have my Vantage pro data logger connected via usb.

What brand? My generic 485 adaptor worked fine, and my keyspan 232 one worked after I installed the driver/app from their website.

Solution from C.Burton (worked for me using WMware!)

I have been told by Davis that the Product ID (PID) for the Mac is 0xEA60 and the PID for Windows is 0xEA61. To solve the problem on the Mac only, you apparently have to get a PC and connect to the Vantage Pro console with the PC. Then you have to perform the following steps to reprogram the PID using the PC using Windows:

1. Install the USBXpress driver on the PC running Windows.
2. Then run AN144SW "CP210xSetIDs.exe" with "CP210xManufacturing.dll" and change the PID from 0xEA61 to 0xEA60.
3. Install the VCP driver on the Mac
4. Now, the CP210x device is ready to be used on your Mac with the VCP driver.

The VCP driver is available for Mac OSX here:

If you run Parallels or VMware or another virtual system to run WeatherLink on Windows, in addition to running WeatherLink on the Mac, you need to perform the following additional step after Step 1 above (note that you do not need a PC, just use the Windows on the virtual machine for Steps 1-4 above and Step 1a below):

1a. Install the VCP driver on the virtual machine for Windows.

The VCP driver is available for Windows here:
http://www.silabs.com/products/mcu/Page ... ivers.aspx

Now, the CP2102 will re-enumerate on Windows under the virtual machine. You will see that Windows is now recognizing it as a Virtual COM port device instead of a USBXpress device. In addition, you should see the CP2102 (with PID = 0xEA60) on your Mac.

Hope this information helps and solves the problem for all of us.
