Thanks Amit. They are connected through a hub. I’ve been reading about the problem of the USB A mini plug and shorting OTG 4 and 5 and actually attempted that without success. I even powered the BB separately from the hub and still no go. I’m about to attempt using an Angstrom u-boot.bin as I’ve read in a 2009 post.
Thanks Geoff. I need to do a few more checks because I discovered to my surprise last evening that no data was passing through the hub, only power. I also picked up a mini-A adapter at a dollar store last night - which will be of no significance if the hub isn’t working. I’ve ordered one on-line and may pass by the store to pick it up today.
