Hi,

I have a USB-powered portable hard drive which I've connected to the BBB 
via a powered USB hub. The hub can supposedly supply 2.5 A, which I think 
should be enough. The light on the drive comes on, but debian on the BBB 
does not create a device for it or try to mount it. That is, there is no 
/dev/sda or anything similar. lsusb shows only:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub


dmesg shows multiple errors like:


56.727916] hub 1-0:1.0: port 1 not reset yet, waiting 200ms

[   56.931012] hub 1-0:1.0: port 1 not reset yet, waiting 200ms

[   57.134166] hub 1-0:1.0: port 1 not reset yet, waiting 200ms

[   57.337258] hub 1-0:1.0: port 1 not reset yet, waiting 200ms

[   57.337303] hub 1-0:1.0: port_wait_reset: err = -16

[   57.337341] hub 1-0:1.0: port 1 not enabled, trying reset again...

[   57.337376] hub 1-0:1.0: Cannot enable port 1.  Maybe the USB cable is 
bad?

I was able to mount the drive on a laptop through the same hub. I had 
previously used the BBB's USB port to connect a keyboard and a mouse 
through a USB-powered hub.

Any advice would be much appreciated.
