I'm with the following problem: i've bought a new PS Jailbreak dongle, did the setup by the book, got serial n/o from the upgrade application and flashed latest version, with all the green lights and success messages required.
After that, I tested the dongle on my ps3 and it failed (I later found out that the console had updated do 3.55 :P ). After that, the dongle wasn't detected by any of my windows 7 (32 bit) boxes or windows XP sp2 when plugged in.
All I get is both lights on (red, green), (fixed, not blinking) and windows *****ing about not knowing the hardware. When attempting to upgrade drivers on 7, it says that the device "doesn't need new drivers", on xp it complaints that the drivers aren't adequate to the device :S
I've tested several routes to get the dongle detected in windows (except the bridging procedure), with no success so far.
In a nutshell, I can't flash my dongle anymore or change it's mode (downgrade/jailbreak) because I can't get it detected in windows. I don't know what caused it and what to do to fix it
Maybe it's just encrypted. Some dongles are. (I belive original PSJailbreak is one of them.) In this case windows won't detect it. You must use their upgrader to flash it. Download PSJailbreak Updater from their official site, run it, and probably dongle will apear in program.
