USB3 won't power 2,5" external HDD
Hi,
I have two 2,5" external hard drives, which I use for backups. So far I have used them with different machines mostly on USB2 ports, never had an issue. So I thought surely the PBP USB3-port must be able to power them, but that does not seem to work. One won't spin up and sits there clicking, the other one does spin up but starts clicking once I try to mount it. So now I bought a USB-C to USB-A converter and hooked the drives up to the USB-C port, and now the one that wouldn't spin up mounts (the other one does still does not mount). I couldn't find any power specification for the USB-ports in the Rockchip datasheet, but I am a bit puzzled because so far even the cheapest netbooks would power these drives even on USB2...
Is this the expected behaviour?
Thanks!
Björn
