I’m trying to connext an older 500GB “my passport” to a raspberry pi, using a powered USB hub.
The passport won’t power up. It clicks. The led does light up.
I guess this is a power issue. My powered hub power supply is a meager 1A. It needs to power both the passport and the raspberry pi. The latter used ~750mA. I cannot figure out what are the passport requirements.
Any suggestions, ideas etc?
I’d also considered some kind of a Y cable that will power the passport, and connect data to the passport, but could not assert that such a cable exists (and I’m not into soldering).
EDIT: I don’t know if the cable will work with a Passport or not (it’s designed for the PiDrive, but the drive does use a USB interface…), but it looks like the cable is being sold standalone now:
Instead of 2 power supplies (one for the hub to power the drive, and one fr the pi), you use only one power supply and the hub powers both devices as well as connect their data ports.
