I have an iMac running OSX 10.6.5.
There have been no hardware changes recently. The only software changes are the periodic updates from Apple that I install faithfully.
Recently it stopped recognizing USB devices that have mass storage except for one -- I have a Seagate Free Agent drive that it's quite happy with. it won't recognize my camera (Cannon) my Android Phone (Samsung) my digital recorder (Tascam) or my usb flash drive. I plug them in and NOTHING HAPPENS on the Mac side. (The devices know they're plugged in.)
Things that I'm pretty sure of:
It is not a problem with the devices. They work with other computers. They have FAT file systems, etc.
It's not a problem with a particular port. I have tried all of 'em, with and without my external USB hub. Also in addition to the Seagate drive which works I have a wireless keyboard & mouse that connects via a USB receiver. I'm using the keyboard now to type this message -- hence USB works.
Yes the devices are getting sufficient power. My phone happily charges while OSX refuses to admit that it exists. My phone and my digital recorder both know that they are connected as a USB mass storage device to a computer.
Disk Utility doesn't show the device. Finder doesn't show the device. IPhoto does not show the camera (it used to a couple of weeks ago.)
Restarting the computer with or without the devices plugged in doesn't change things.
So what do you do when "It just works" doesn't work? Is there any way to manually tell OSX that it should pay attention to the USB device I just plugged in.
I'm stumped and can't think of anything else to try. Suggestions? Miracles?
