No USB keyboard or WiFi after Mt Lion Upgrade

Since upgrading to mountain lion from the latest version of Lion, I no longer have USB or Wifi support it seems. My 2008 mac pro doesn't recognise when I plug anything except a additional wired mouse, and I can only get that to work if its plugged in at boot. Also the second mouse is extremely laggy and is almost impossible to click on anything. I can still use my keyboard to get into verbose/single user/ reset pram on boot, but after that both the main OS and recovery are useless. The only error I see is when I use single user mode. After the OS has loaded after a couple of minutes I get some text on screen that says IOUSBfamily is having trouble on port 2 (where my keyboard is plugged in) This is driving me crazy. I did make a backup and I have a spare hdd in my mac pro with lion on it, and am still able to boot into that and everything works fine.


Is anyone else having this kind of problem, and is there anyway to remedy it?


Here are my specs


Mac Pro 2008 2.8ghz

ati 2600 xt (boot + secondary monitor)

ati 6870 (primary monitor 1900*1200)

8 gig of ram


HDD slot 1: mountain lion/Applications running on 128gb ocz SSD

HDD slot 2: users are located on a 1 TB HDD


I've tried disconneting all USB ports, removed extra hdd's, dvd drives, graphics cards and nothing works.

Having worked with Apple engineers on this I can report the following...


My MacPro 2008 wouldn't work with ML. No Wifi and no USB.


The problem is down to having the wrong version of the Airport Card fitted to the MacPro. If you are having issues then you need a newer version of the Airport Card, I believe an N version.


As support was dropped for older hardware the AirPort card you have is out of date and should not be fitted to the 2008 Mac. It was designed for older Macs and is not officially supported by Apple, hence why its messing up USB.


To test if this solves your problems, shut down, remove AirPort card and reboot. If everything now works we know where the issue is.


To buy a newer AirPort card you will either need to go to an Apple Store and have them order you one or you can look on Ebay to find a later model card than the one you have.

FOUND A FIX!


Ran into this weird issue after Finder hung up on me trying to access an external USB drive.


After reading all the posting in here, I removed all attached USB devices with the exception of apple aluminum keyboard and mighty mouse. Reboot and voila! I was able to log in using my keyboard.


I turned off WIFI (I'm connected directly to my router via GBE) and reattached everything. Everything appears to ba back to normal.


Hope this helps.


Cheers

THANKS A TON!!


the 'b' sequence actually helped me out - i got iMac 8,1, decided to do clean install of ML ( previous upgrade from Lion which was an upgrade from SL worked without any problems )


bit of rephrasing : its rather reinstall than reload of os from recovery menu 🙂 (which requires another... 4gb download from MAS, but oh well... )


so thanks again!

Did the upgrade to ML today. Bad idea. Same issue.


Solved removing all usb devices connected and plugged only the keyboard directly to the MAC.


Strangely the problem was not present until the 10.8.2 supplemental upgrade n. 1.


If I reconnect the usb devices like the hub inside my Dell primary monitor the problem comes again out.


I don't want tu unplug the wifi card! Will apple release a decent software fix before we all die?


Doh!

No Apple are not working on a software fix. The card is no longer supported and should not be in any ML capable machines. I have spoken directly to Apple engineers about this, as we worked through the issue.


Unfortunatly for what ever reason you have an older AirPort card and need a replacement. You can go through Apple and order one or get on from Ebay. Fitting is easy enough, take a pic before hand so you can see which points the arials connect to if you are unsure, otherwise it just slided out.

Thank you Matthew.


I removed the wifi-card but the problem is still there (the card was an apple card).


Anyway I think that my problem was the Hub in the Dell Monitor, bacause when I changed with another Hub I had my keyboard mouse and bamboo tablet working again. Now I have a MacPro without wireless card... Doh!


It's hard to believe that they cannot solve this via software. I think the don't want to do it.

In the meanwhile we are still waiting for some real new macpro.


Thanks again!
