Hi,
I wanted to reply to the Linux mailing List (your patch thread), I
dont know exactly where since the addresses are blanked out.
Just tell me where I should move this discussion.
The board can use both USB peripherals (haven`t tested the OTG Port).
The issue starts if the board has *no* USB peripherals attached
(either booting without any USB peripherals, or disconnecting all
peripherals).
I have checked my patches with kernel next-20160923, I didn't meet your
problem. The firefly RK3288 release board works fine.
*Then* I cant connect a single peripheral, just getting read errors.
Seems like something is getting powered down if no USB peripheral is
connected, and can`t start up again.
Kind regard,
Norbert

sorry for stalking you, but I have a problem with the USB Ports on
You have better CC to Linux-use as well
RK3288 and Heiko pointed me to your patch [1].

I can easily reproduce the issue, if no USB Device is connected then
attaching USB Devices will produce Read Errors.
The only way around that is to always leave one device connected.
So the board could only connect to use one usb peripheral device?
