New Revision: 364433
URL: https://svnweb.freebsd.org/changeset/base/364433
Log:
Fix regression after r364379.
The AMD's Ryzen 3 3200g XHCI controllers apparently need the evaluate
control endpoint context command, but we don't need to issue this
command when the bMaxPacketSize is received after the read of the USB
device descriptor, because this part should be handled automatically.
