usb: r8a66597-hcd: fix cannot detect low/full speed device

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

 



This controller can control "Transaction Translators", but the hcd->has_tt
is not set. Since the commit "d199c96d41d80a567493e12b8e96ea056a1350c1"
has checked it, the driver could not work the low/full speed device.
