I have the AT90USBKEY (AT90USB127) and am using the flip software. I have succesfully flashed several versions of both openpsjailbreak and psgroove to the device.
However the PS3 just does not like it! The PS3 usually comes up with the error USB device not recognised in the top corner and nothing new appears in the games section
I have also noticed the red light NEVER goes out of the USB KEY. On all the videos on youtube the red light goes out after a few seconds of turning on the PS3 and then pressing eject.
My PS3 is running software version 3.30...could this be causing the problems? The current version I think is 3.41.
Any help on this would be very much appreciated as I am going slowly insane!
