+AD4- +AD4- Hello,
+AD4- +AD4-
+AD4- +AD4- Looks like this is another manifestation of already seen problem with ath9k-htc
+AD4- +AD4- and OHCI controller.
+AD4- +AD4-
+AD4- +AD4- I'm trying to get USB Wi-Fi dongle based on Atheros AR9271 to work with our
+AD4- +AD4- development board (this is Synopsys AXS103) and seeing a picture very similar to
+AD4- +AD4- what was discussed here http://thread.gmane.org/gmane.linux.usb.general/110847
+AD4- +AD4-
+AD4- +AD4- Below is what I see on insertion of the dongle.
+AD4- +AD4- Note I have the most recent ath9k-htc firmware (see +ACI-ath9k+AF8-htc/htc+AF8-9271-1.4.0.fw+ACI-
+AD4- +AD4- in the log below) and Linux kernel is 4.6.3 (latest stable as of today) but the same
+AD4- +AD4- happens even on 4.4.
+AD4- +AD4-
+AD4- +AD4- Interesting enough if I simply remove or disable the warning like that

+AD4- please send content of hif+AF8-usb+AF8-send+AF8-regout() from your source code.
+AD4- It is located in drivers/net/wireless/ath/ath9k/hif+AF8-usb.c
I use vanilla 4.6.3 tree so that's what I have is the same as
