USB drive not recognised unless disconnected/reconneted

[mrochester]

Hi all

I've found that if I plug a USB drive into my MacBook Pro while it is asleep or just waking from sleep, OSX will not detect the drive until I unplug and reconnect it again.

Does anyone know what the problem is and why the drive doesn't just appear?

Many thanks

Probably because when the Mac is asleep, or in the process of "waking from sleep", the USB controller isn't "ready" to recognize newly-connected drives yet.

Solution:
Wait until the Mac is "fully waked up" and then plug in the drive...

Bummer. It's only mildly irritating and thought there might be a way to fix it.
