Re: Adding external HDD to Raspberry Pi
I've got this one: http://www.dynamode.com/english/pages/product/Datacom%20Products/USB%20Products/USB-H40-A2-0.html when I connected this device to the Raspberry I got these message Dec 17 13:59:48 pi kernel: [246075.608736] usb 1-1.4: new high-speed USB device number 112 using dwc_otg Dec 17 13:59:48 pi kernel: [246075.710412] usb 1-1.4: New USB device found, idVendor=05e3, idProduct=0608 Dec 17 13:59:48 pi kernel: [246075.710447] usb 1-1.4: New USB device strings: Mfr=0, Product=1, SerialNumber=0 Dec 17 13:59:48 pi kernel: [246075.710462] usb 1-1.4: Product: USB2.0 Hub Dec 17 13:59:48 pi kernel: [246075.721467] hub 1-1.4:1.0: USB hub found Dec 17 13:59:48 pi kernel: [246075.721944] hub 1-1.4:1.0: 4 ports detected When I connected the HD to it the syslog was filled with this message: hub 1-1:1.0: over-current change on port 2 but I still could not see it using sudo fdisk -l Gabor ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

If you don't use an external power source, it is in passive mode, which means the overhead of the hub, and all of the devices plugged into it can not be more than what the port supplies. I don't know what the Pi supplies, but the official standard is 500ma for USB 1 and 2. If you plug it in, it will support the full 500ma (possibly more) to each device. Since it is a 4 port hub, you want a 2000ma (2 ampere) supply. Personally, I prefer the Apple 12 watt chargers as they really do supply slightly more than 2 amps without burning up. They are expensive, but IMHO worth it. Geoff. -- Geoffrey S.

If you aren't afraid of opening your phone and soldering you will probably find it has debug ports/jtag which would allow you to dump the contents of the memory, there may also be a recovery mode... Will be happy to --open solder, if only I can find how the jtag (or whatever) works on this phone. I have been told that it may be encrypted by default.
