I managed to put a psgroove hex on my USB a few days ago, but I'm still on 3.50 so it didn't work. I realised this later, and I found a downgrader beta release (I'm willing to try it now) and I need to put a hex file onto my USB. However, when I use FLIP (by atmel) I load up my USB - AT90USB162, and load up the hex file.
However, when I click Open usb connection, it says "Could not open USB Device." I've researched a lot, installed many drivers and it doesn't work on my laptop, pc or my brother's laptop.
I have windows 7, but on this laptop the driver won't install. I've downloaded many different ones for PSJailbreak...
Additional Info: When I put the usb into my fat ps3 and press power then eject, it beeps 3 times but both red and green lights stay on. There is also a second green light.
When I put the usb into my pc, all of the lights are on.
I have the olimex board, to put it in FLIP mode, I need to press the big button and hit the reset (while holding the big button). Then it is recognized as a FLIP device. Also, when you are using windows 7 x64 or vista x64 you need to install the signed x64 drivers. The standard flip fails at installing the drivers, but does not report this. You will need to look for the x64 drivers, they might be on the avrfreaks site. (hint, google it)
