I'm planning to jailbreak my PW2. But, if it is possible, I would like to avoid ordering one of those dedicated usb serial adapters. So could one use other things like a Raspberry Pi (it has some IO connectors) or another Kindle (K3) as serial "adapter" to get into PW2?
Another question: are all the kindle models' serial ports compatible with a same adapter?
