I'm a little unclear about USB Video Class (UVC). In order to use the
camera, does it need to have a Video4Linux driver that "talks" to a
UVC class or it is possible to have a camera that doesn't have a
Video4Linux driver and interfaces to a UVC directly?

uwbd_start() calls kthread_run() and checks that the return value is
not NULL. But the return value is not NULL in case kthread_run() fails,
it takes the form of ERR_PTR(-EINTR).
Use IS_ERR() instead.
Also add a check to uwbd_stop().

uwbd_start() calls kthread_run() and checks that the return value is
not NULL. But the return value is not NULL in case kthread_run() fails,
it takes the form of ERR_PTR(-EINTR).
Use IS_ERR() instead.

We are developing a product based on the TI AM5728 EVM. The product utilizes a
TUSB7340 PCIe USB host for additional ports. The TUSB7340 is detected and
setup properly and works OK with low data rate devices. However, hot plugging

Hi, thanks for recreating and looking into this. What I've done is
disabled powertop auto tunables as a system service and then looked at
that value. With powertop not running it is indeed set to ON for both
