[meta-ti] BeagleBone Black: cannot access USB MSC devices

[Patkar, Sarvesh S.]

Hi Denys,

Thank you for the quick reply.

I tried the core-image-base. I see the following on the console.

root at beaglebone:~# lsusb
unable to initialize libusb: -99

fdisk doesn't list the USB device as well. 

Is there anything else that I can try?

Thanks,
Sarvesh

Please don't use core-image-minimal (e.g. core-image-base is much better), if you want to get anything useful out of it, besides just booting, including such tools as fdisk, lsusb, etc. Thanks.
