+As reported by Randy we can overwhelm logs on some USB error conditions.
+To avoid that use dev_warn_ratelimited() and dev_err_ratelimitd().

+Date: Tue, 12 Mar 2019 10:51:42 +0100

+Some USB host devices/drivers on some conditions can always return
+EPROTO error on submitted URBs. That can cause infinity loop in the
+rt2x00 driver.
+
+Since we can have single EPROTO errors we can not mark as device as
+removed to avoid infinity loop. However we can count consecutive
+EPROTO errors and mark device as removed if get lot of it.
+I choose number 10 as threshold.
