Hi all,
this is a re-submission of Bin Liu's patch that was reverted by the commit 16b61d13bab361853564da401b15fc34ae1dfea7 from Daniel Mack.
It is not OK to set the MUSB_POWER_HSENAB unconditionally because there are sometimes some HW limitations that allow only FULL SPEED.
In our case we have some bad wiring protection in our USB circuit that acts as a filter an will not allow signals to pass that are faster than FULL SPEED.
I suggest to use CONFIG_USB_GADGET_DUALSPEED define to enable HIGH SPEED as it was done previously, which is by default enabled.
Kind regards
Sam
