flashed hermes v4b hex, now device isn't working help?

like the title says, I flashed hermesv4b avropendous at90usb162 8Mhz.hex to my jb device... when I plug it into my ps3, press power then eject it lights up green... however, I'm unable to run homebrew. So I was gonna flash another hex file... now xp doesn't even see the device as connected to my machine... nothing shows up in device manager, thus i'm unable to erase the chip...

any help would be great...

You have a ps3jailbreak? I thought those only worked with the PS3JB hexes. If that's the case then you probably just whacked your jb device.

I could be mistaken though. I use an AVRKey.
