Honored ContributorHow to enable USB with Linux 4.11 and DE2-115
I can boot Linux 4.11 with Altera DE2-115. I want to enable USB. How can I know where the problem is?
I added a USB in QSys but I can't verify that it actually works. I also added USB in menuconfig to the kernel. I can see that it loads the driver but the USB doesn't appear in /dev when I check it. Is there a way to find what change to make? When I've done the change in QSys, shouldn't it appear in Quartus in the block design?
Linux version 4.11.0-rc6-00200-gd5ff081 (developer@1604) (gcc version 6.2.0 (Sourcery CodeBench Lite7
