Mac Mini OSX 10.9 IO peripherals are not working after deleting iousbfamily.kext

Hi,
My Mac-Mini is having an issue with wireless and USB peripherals after removing, IOUSBFamily.kext, IOUSBMassStorageClass.kext,
IOFireWireSerialBusProtocolTransport.kext
After reboot, I could not login or access my machines using the keyboard or mouse.

Is there anyway that I can recover this issue.? Could someone help me on this please.?

Thanks
Nandhu

I have to ask... why did you remove those kernel extensions? The only way I know how to recover is to reinstall Mavericks. Boot your Mini to the Recovery Partition (hold down command + r keys) and from there either restore Mavericks from your Time Machine backup, or if you haven't been making backups, download and reinstall Mavericks from Apple.

Thanks for the reply.

I was trying to disable the USB ports for a testing but accidentally I removed the IOUSBFamily.kext file too and rebooted.

If you're using a wireless keyboard and mouse, they won't work in that situation. You need a wired keyboard and mouse until Mavericks is reinstalled. You can use any wired USB keyboard - even a Windows model, and any USB wired mouse.

Vital equipment USB kb and mouse even in this wireless age.

Thank You All. My issue got resolved.

I was not having time machine backup or partition or internet, Luckinly I was having those deleted files in my Trash. I logged in the boot option (Command + R) and used Terminal utility to move back my removed files to original place and manually rebooted.
Now my system is back and running good. Thanks once again.
