Hi Alan,
I reworked the warm reset patches, could you take a look at them?
Changelog:
- Added xHCI roothub port polling when a change bit is set.
- Removed patch to unconditionally clear all change bits on USB 2.0
port disable, since the port polling should now take care of that.
- Reworked the second patch description to make it more clear why it's
necessary to ignore errors for the xHCI Reset Device command.
- Changed the patch to ignore port state until the reset is complete to
do that for all speeds of hubs.
- Broke the final patch "USB: Fix connected device switch to Inactive
state." into the last four patches. Hopefully this is more readable.
Unchanged patches:
USB: Handle auto-transition from hot to warm reset.
USB: Ignore xHCI Reset Device status.
USB: Allow USB 3.0 ports to be disabled.
USB: Increase reset timeout.
USB: Handle warm reset failure on empty port.
Thanks,
Sarah Sharp
