USB and Kernel 3.18-rc7-bone1 #10

Closed asymingt closed 9 years ago

Are there any known issues with USB on 3.18-rc7-bone1?. I have tried both DMA and PIO mode without luck, as well as compiling MUSB/Gadget together as modules and directly into the kernel.

Here's the error I get on booting / through dmesg:

[    8.548618] random: nonblocking pool is initialized

And I can't list USB devices:

root@arm:~# lsusb

Here's my kernel config: http://pastebin.com/Hi7U2xSD

Well, you have phy disabled:

# CONFIG_AM335X_PHY_USB is not set

That is extremely embarrassing. Thank you.
