The USB controller is chipidea one .
The drivers are all chipidea opensource driver.
I have a requirement of connecting Iphone to it , where it will launch
carplay on detection of carplay device .
The flow is :

Hello,
I ran into an issue with a Xilinx Zynq XC7Z010 system. The system acts as a
USB peripheral, using the UVC gadget driver.
When transferring high bandwidth data over USB in isochronous mode, complete
system freezes are occasionally noticed. The problem was traced to the
following code fro

Hi
I got this bug : using last kernel on Archlinux (4.10.13-1, since 4.4),
an USB 3.0 external HDD dies all the time when writing on it.
If you write slow, it works, but with high copy, it freezes.
Tested on multiple computers, multiples disks, and multiple external disks.
On dmesg I got this :

Hello everybody,
