I bought 2x H240 adapters on eBay. One was perfect, HBA mode with latest firmware, no issues. The second one I can't get to work (asked for replacement but taking a while). The card isn't totally dead, I can feel the heatsink is getting warm so it is drawing current. In windows it shows up as "RAID Controller" but no drivers get it out of it's yellow exclamation point. No HP windows or linux utilities seem to recognize it. Any ideas if I can try something to bring it back to life?
