My Epson perfection 4870 isn't recognised by mountain lion
I've been running an Epson Perfection 4870 Photo scanner on an older iMac in Snow Leopard by firewire. I 've now got a new iMac running Mountain Lion and I migrated the data from the old Mac. As it no longer has firewire I hooked up the scanner using USB. The scanner doesn't seem to be communicating with the iMac and the software update says that there is no update available. Has anyone any ideas as to how I can get my scanner working again?
iMac, OS X Mountain Lion (10.8.2)
