Hello, Looks like this is another manifestation of already seen problem with ath9k-htc and OHCI controller. I'm trying to get USB Wi-Fi dongle based on Atheros AR9271 to work with our development board (this is Synopsys AXS103) and seeing a picture very similar to what was discussed here+AKA-http://thread.gmane.org/gmane.linux.usb.general/110847 Below is what I see on insertion of the dongle. Note I have the most recent ath9k-htc firmware (see +ACI-ath9k+AF8-htc/htc+AF8-9271-1.4.0.fw+ACI- in the log below) and Linux kernel is 4.6.3 (latest stable as of today) but the same happens even on 4.4. Interesting enough if I simply remove or disable the warning like that ------------------------+AD4-8--------------------------- diff --git a/drivers/usb/core/urb.c b/drivers/usb/core/urb.c index 3d27477..a317e1e 100644 --- a/drivers/usb/core/urb.c +-+-+- b/drivers/usb/core/urb.c +AEAAQA- -443,11 +-443,6 +AEAAQA- int usb+AF8-submit+AF8-urb(struct urb +ACo-urb, gfp+AF8-t mem+AF8-flags) +AKAAoACgAKAAoACgAKAAoACgACo- cause problems in HCDs if they get it wrong. +AKAAoACgAKAAoACgAKAAoACgACo-/ +AKA- -+AKAAoACgAKAAoACgAKA-/+ACo- Check that the pipe's type matches the endpoint's type +ACo-/ -+AKAAoACgAKAAoACgAKA-if (usb+AF8-pipetype(urb-+AD4-pipe) +ACEAPQ- pipetypes+AFs-xfertype+AF0-) -+AKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACg-dev+AF8-WARN(+ACY-dev-+AD4-dev, +ACI-BOGUS urb xfer, pipe +ACU-x +ACEAPQ- type +ACU-x+AFw-n+ACI-, -+AKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoA-usb+AF8-pipetype(urb-+AD4-pipe), pipetypes+AFs-xfertype+AF0-)+ADs- - +AKAAoACgAKAAoACgAKAAoA-/+ACo- Check against a simple/standard policy +ACo-/ +AKAAoACgAKAAoACgAKAAoA-allowed +AD0- (URB+AF8-NO+AF8-TRANSFER+AF8-DMA+AF8-MAP +AHw- URB+AF8-NO+AF8-INTERRUPT +AHw- URB+AF8-DIR+AF8-MASK +AHw- +AKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACgAKAAoACg-URB+AF8-FREE+AF8-BUFFER)+ADs- ------------------------+AD4-8--------------------------- everything seem to work quite nice.
