Wired aluminum keyboard not working with 2010 iMac
Hello all,
So I bought an iMac on dec, 2010 it came with snow leopard and a wired aluminum keyboard, everything was good until dec, 2011 when my keyboard suddenly stopped working, I took it to an apple store and they replaced it, everything was fine until last month when my new keyboard stopped working again.
I have an old macbook (1st gen of intel-based macbooks) and if I connect the keyboard to that macbook it works just fine, I have checked and all the USB ports on my iMac and they work but when I connect the keyboard it just doesn't recognizes it as a keyboard (or as anything because it doesnt show on system profiler). I have connected another keyboard I own (a logitech wireless one) and the imac recognizes it, I don't know what to do.
Anyone knows how to fix this?
Btw, if I disconnect the keyboard for a day or two it works again when I connect it to the iMac, also If I use the USB ports attached to the keyboard I get an error that the USB is taking too much power and it shuts down (and then the keyboard stops working again on the iMac)
iMac, Mac OS X (10.6.8)
