I booted my laptop up this morning and it said it had found new hardware (Cypress AT2LP RC42).
It turns out this is my external hard drive, one I bought a couple of months back. It's a Freecom one, which was working fine last night, however now doesn't appear as it can't find drivers?
I had a look about and it sounds quite common, something to do with the laptop not getting through the enclosure?
Mean anything to anyone?
