/* This is a version of usb_clear_halt() that doesn't read the status from

- * when the status is requested after a halt
+ * when the status is requested after a halt.
+ *
+ * A definitive list of these 'bad' devices is too difficult to maintain or
+ * make complete enough to be useful. This problem was first observed on the
+ * Hagiwara FlashGate DUAL unit. However, bus traces reveal that neither
+ * MacOS nor Windows checks the status after clearing a halt.

+ * Since many vendors in this space limit their testing to interoperability
+ * with these two OSes, specification violations like this one are common.
