Silicon Labs indicated that some how, based on System Profile information, the Product ID was changed from 0圎A60 to 0圎A61, thus pointing to the USBXpress driver and not the VCP driver. The System Profile still shows the same CP2102 entry. touch /System/Library/Extensions, and reboot. I decided I should perform an operation I read about, i.e. I looked in /System/Library/Extensions and found the SI Labs kernel extension SiLabsUSBDriver.kext. The CP2102 driver still does not show in the /dev directory (either as cu.CP2102. Reinstalled the Si Labs driver package, and restarted. Performed a Mac reset of SMC and PRAM, with no joy.Ģ. and tty.) cannot be found (or possibly is not installed).ġ. So, the CP2102 is being recognized, but the driver (cu. Vendor ID: 0x10c4 (Silicon Laboratories, Inc.) I expanded each of the USB entries and found the one that shows the CP2102.
I opened System Profile and clicked on the USB selection. I scanned the various logs over the half hour of the install process, but did not see anything else of interest. I did notice that the CP2102 gets turned off after 10 seconds of no activity several times in the past in Kernel log, but not as a result of this set of installs. I did not see any problems in those logs over the installation timeframe. I searched Console, Kernel, Install, and System logs for CP2102, among other things. Not sure if this is the reason that the CP2102 is not being seen. usbserial-FTCUSRHZ, and showing the same NetBIOS Name). Under the WINS tab, it lists the CP2102's NetBIOS Name as IMAC-C7DFF1 and indicates that name is currently being used (possibly by another USB to UART adaptor I use to talk to an old Garmin, i.e. Clicking on the Advanced button, it shows the CP2102 as an Apple Modem. The shows up as a grayed out Modem with Inactive Status. I looked at System Preferences, then at Network Preferences. OSX_VCPDriver.zip), performed the installation, and restarted.
I went to the Silicon Labs web site and downloaded the VCP driver kit that is used to talk to the Davis device ( The driver was working on 10.4.11, but after I upgraded to 10.6.2 it is no longer recognized and does not show up in /dev, i.e. I have been working with Silicon Labs and Davis Instruments to try to get this driver installed on my iMac without any success.
