I have been having intermittant keyboard and mouse glitches when connecting mouse and keyboard peripherals to my MacBook Pro (circa 2010) through the 27" cinema display (circa mid 2011). While not entirely sure, this seems to have started happening either after 27" firmware update OR bootcamp reinstall. I have gone through the procedure of SMC reset and PRAM reset, same symptoms. Microsoft wireless mice are unusable. Logitech wireless mouse seems to work reliably now. Apple keyboard consistently types multiple characters after restart.Have tried two same model Apple keyboards and have seen similar symptoms on both.Mouse and keyboard are low power usb devices.Assuming that usb hub in 27" is a powered monitor. Symptoms seem similar to USB power supply failure. Was their any change to USB hub firmware in firmware update?Anyone experiencing similar issues?
