I heard many said that e3 card reader has this causing ps3 to freeze while playing game after an hour or so and ps3 shows it as an unidentified device.(when used as a jailbreak dongle)

is this true tho? cuz i was looking forward to buying this card since it super noob free drag-and-drop update. however after hearing all this, i am really worried. should i? I need some answers!

thanks in advance!
