Hi Alan,
Do you mean that if you plug in a new USB device, nothing happens?
Or do you mean that some USB devices which were present during boot
don't get detected?
The first, when I plug in a new USB device.
Are the undetected devices attached to a USB-2 port or a USB-3 port?
I can

Hi Florian,
This is just a suggestion, but.. maybe you have a hub between a host
and a device?
In such case you need to enable remote wakeups for it. For example,
using your little script:
for i in `find /sys/bus/usb/devices/*/power/wakeup`; do echo enabled $i; done;

Best regards,

Here's the problem we face: The class driver submits packets 1, 2, 3,
and 4. They get sent properly, but the completion interrupt is
delayed. As a result, the class driver's completion handler doesn't
get called until too late; the frames for packets 5 - 44 have already
expired. The data

There were still some corner cases where isoc transfer was not able to

not queue any new request during giveback.
Cleanup function calls giveback first, which provides a way to queue

Update transfer is issued for the TRBs where HWO switches from 0 to 1.
Lets say we had issued START TRANSFER with 8 TRBs having HWO as 1. Now
we need to update 9th TRB, Then we need to call UPDATE TRANSFER with
parameter as 9th TRB.
Current code was issuing UPDATE transfer with 2nd TRB, which was
Now do not return from start_isoc if request_list is empty. You are

We are clearing resource_index when we issue END TRANSFER command.
Consider a situation, when we have executed END TRANSFER, core has
generated xfernotready, but gadget is too slow and have not queued
any request. So we set PENDING flag. Now application queues another
request. Software does not

There is a possibility of QH overlay region having reference to a stale
qTD pointer during unlink.
Consider an endpoint having two pending qTD before unlink process begins.
The endpoint's QH queue looks like this.
qTD1 -- qTD2 -- Dummy
To unlink qTD2, QH is removed from asynchronous list and
101 - 119 of 119 matches
