No USB keyboard or WiFi after Mt Lion Upgrade

I have exactly same problems with my 2008 Mac Pro. No USB, No Wifi and wont boot from a USB or CD.

I too have really laggy wired mouse ( not and apple one, apple keyboard and mouse wont work at all ) even in the boot installer. Its like the USB drivers dont support my machine.

I have managed ( many hours of slowly moving mouse and tabbing where its still supported ) to format the disk and the installer from recovery partition is now downloading again.

Same problem. Same Mac.

I'm not getting any power to my keyboard or mouse. If I startup with the mouse in the front USB slot I will get power upon startup, but the mouse will be laggy and unusable as the OP said. I can't login at all however because my keyboard does not work.

This is now serious! Excatly the same problem, Mac Pro 3.1.

10.5 - OK, 10.6 - OK, 10.7 - OK, and version in between, and now 10.8 - USB problem on Mac Pro 3.1.

What is the problem Apple ?

Have esculated this with Apple Support Engineers ( not teir 1 ) and they are looking at the logs and some other stuff of my machine.

I also did a clean install and that didnt work so dont bother doing that as you will just lose all your stuff.

I will report back once I know anything of use.

I really can not understand these type of problems.

Like Apple developers did not try Mountain Lion on Mac Pro 2008, which is EFI64, and fully supported machine....

No probs, just sharing 😀

I did upgrade on top Lion, clean install on two disks....nothing works.

I even tried to switch IOUSB kexts...nothing.

Some tried and true approaches.. repair permissions then reboot.. then delete the Wifi service "-" in System Preferences and the recreate the Wifi service "+".

My WIfi and USB works fine.

Do you have Mac Pro 3.1 ?

Which excact build of Mountain Lion did you install ?

I installed off the App Store.

I made an appt to take my Mac Pro to an Apple Store tomorrow. 😟

I have the same problem !!! It's crazy, I spend all day try to install Mountain Lion from Mac App Store and nothing work. After upgrade from latest Lion I see login screen without cursor, mouse not responding and Apple USB Keyboard too... I cant login...

I try with Magic Mouse and Apple Wireless Keyboard, but Bluetooth is disable or not working (in Lion before installation i use mouse and keyboard via Bluetooth).

I try via USB Logiteh LX3 mouse and Apple USB Keyboard - not working...

Wi-Fi not working too, the same problem like.

When USB mouse is connect after about 5 minutes on login screen (clock work and i see minutes changeing in top corner) cursor showiing up but keyboard still not working and I cant write password... Madness!!!

It's very serious, almost everyone with Mac Pro 3,1 (early 2008) have the same problem with USB devices and I/O !!!! Apple please do something !!! or I will stay with Lion and fight for money back... It's not right - in specification of Mountain Lion Mac Pro early 2008 still is on the list...

I try install via Mac App Store but problem shows...

After this I recover via Time Machine OS X Lion 10.7.4 - everything work properly than...

After I try install clean copy via USB stick, but when I try boot after 1 ~ 2 minutes Apple logo change to crossed circle and nothing happend...

So my last shot... I try to clean install via online recovery but thanturnedoutin Recovery Wi-Fi not working (shows info that Wireless card not installed but there is inside MAc Pro) so I moved all equipment to acces point and connected via ethernet cable... I hoped thal will solve my problem and I will have Mountain Lion today... but when I open online recovery I had to type Apple ID !!!! but USB keyboart not workin too in recovery mode !!!!!!! grrrrr

I calmed down and I try typing my Apple ID and password by copy and paste by one letter from texts in Mountain Lion instalator using mouse right click... big problem was @... but I found in license...

So it worked, Mountain Lion online recovery finished and I see country list... USB mouse is responding to movment but cursor shows static (not rotate) rainbow circle and USB Apple Keyboard not working... I can'tgo even one step of the wizard...I try many reboots but nothing help...

Obviously there is something wrong with the installation of Mountain Lion because, after returning from a Time Machine to 10.7.4 everything is working properly !

Apple do somethingquickly, baceuse we - Pro users very need our machines to be perfect. It'sa matter to be or not be in professional work!

My machine configuration:

MacPro 3,1 (early 2008)

2 x 2,8GHz Intel Xeon

8GB RAM (800MHz) DDR2 FB-DIMM

ATI Radeon HD 5770 with 1GB of GDDR5

AirPort Extreme

Bluetooth - standard

Now I scared to install Mountain Lion on my iMac middle 2011 (iMac11,3) I don't have any time to lose...

Sorry I'm not very tech savvy. Can you give me instructions on how you restored to Lion from Time Machine without your keyboard or mouse? I'm not sure how to do it.

I would like to go back to Lion until Apple fixes this.

I use one of 4 HD disk in Mac Pro for Time Machine, So I do not have to use Wi-Fi or USB disk for Time Machine it's faster way... USB Mouse is working for me in 10.8 Recovery Mode but Keyboard not, so only by clicking choose option to recovery from latest backup in 10.7.4...

If you have the same problem with USB or Wi-Fi and you use Time Capsule or USB disk for Time Machine... than you have a big problem :/

Folks, call to Apple Support - they take your notification, if you pay for OS X Mountain Lion in Mac App Store you can have support for this software.

I called today and they accepted my notification, if you call too they faster repair this problem baceuse it's looks like bigger problem when more than one person have the same symptomswith MacPro3,1.
