[PATCH] RFC - xhci-hub: Roothub USB2.0 descriptor for BESL DBESL

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Modified xHCI roothub descriptor to return USB2.0 extension descriptor
with BESL and DBESL values set when these values are set on the xHCI
host.
 
Curretnly the root hub device descriptor values are set to zero by the
BIOS. Therefore to test this functionality with lsusb, I hard coded
the usb2_rh_dev_descriptor (not include on patch) to set the bcdUSB
bit to 0x01.

I consulted Sarah Sharp and she is investigating on a solution so
that this value is updated according to the device added.
