I have the following configuration: A Raspberry Pi model B connected to a powered USB hub, with the +5V detached from it (otherwise the hub powers the Pi due to backfeed). They work fine together and I can plug in many hi-powered devices, such as wifi adapters.
I want to connect to it an unpowered external western digital harddrive. When I plug it to my laptop it shows up as:
1058:1010 Western Digital Technologies, Inc. Elements External HDD
However, when I plug it to the powered hub on the Pi it shows up as:
13fd:160e Initio Corporation
/dev/sdd file is not created. It is inaccessible.
I will note that if I connect the powered hub to my laptop, with +5V removed it also shows up as
Initio Corporation. So this probably not a Pi specific problem, but due to it I can't access this drive with my Pi, as I would like to.
How can I get this drive to work with my Raspberry Pi.
