Title:
Ubuntu 15.10 fails to boot from Sandisk USB stick
Status in linux package in Ubuntu:
Confirmed
Bug description:
Booting from Sandisk USB stick fails and stops on "device descriptor
read/64, error -71" and "device not accepting address 6, error -71" on
Dell Latitude E5420 Laptop. I tried every USB socket but without
success. Booting with "rootwait" parameter does not help either.
