XM Driver Install Problem

**MikeH** · 04-23-2005, 08:18 PM

I have been trying to install the FTDIUSBSerialDriver for the XM Radio but it is apparently not installing properly. Each time I install the driver and reboot, I get an error message saying:"System extensions cannot be used: The system extension "/System/Library/Extension/FTDIUSBSerialDriver.kext" 9s installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update". I have re-installed the driver several times with a "driver successfully installed" message after each installation. After looking at the forum at MacXM, I tried the Disk Utility/Repair Disk Permission, after which I would reboot and be greeted by the original "System Extension cannot be used" error message. When trying to run the MacXM application it says it can't find the radio, which tells me the driver is not working properly.

Can anybody shed any light on this?

Have you gone into the System Preferences and checked the box next to the port under Network Port Configuration?

That sometimes needs to be done to get it active and working.

hmmmmm

try this

sudo chown -R root FTDIUSBSerialDriver.kext
sudo chgrp -R wheel FTDIUSBSerialDriver.kext

or if you are lazy and don't know where the files are

sudo find FTDIUSBSerialDriver.kext -type f -exec chmod 644 {} \;
sudo find FTDIUSBSerialDriver.kext -type d -exec chmod 755 {} \;

just something i pull form some forum in a quick

MacXM uses a USB connection, not an ethernet connection. The USB device shows up in the System Profiler, which means the driver IS loaded and the device IS working.

sudo chown -R root FTDIUSBSerialDriver.kext

I'm afraid you're a little over my head with this.... what is it we're trying to do here? Are we looking for the driver to be in a certain location? I'm thinking MacXM is looking in one place, and the driver is installed somewhere else.

Thanks for the help.

I know what it is, I have one. Very aware that it uses USB and not Ethernet.

The Network pane is for much more than Ethernet, it is for many types of connections. Airport, USB, Bluethooth, etc.

DerekICT,

Thanks for helping learn to navigate the Mac. Mine doesn't show the USB connections like yours does. I assume this is the root of my problem..... they aren't being installed in the right place. Any ideas?
