Date: Sun, 24 Jul 2016 15:51:01 +0100 [thread overview]
Message-ID: <CAPweEDzap+wRsPUZLOmBeKFetCVezC8bUdQ4J+APUMgGGZ3L_g@mail.gmail.com> (raw)
hi folks, we're running a crowdfunding campaign live at the moment on
crowdsupply so it is a little more prominent than usual debugging
issues: ath9k_htc has the "unable to allocate urbs" issue which has
cropped up a number of times in the past, since 2013 and even 2010.
i'm plugging in a powered USB3 Hub into the OTG port (set up as a USB
Host). the OTG port is USB2. (i don't yet have access to a powered
USB2-only hub)
this is what i get:
[ 146.752856] usb 5-1.4: new high-speed USB device number 7 using musb-hdrc
[ 146.931295] usb 5-1.4: ath9k_htc: Firmware ath9k_htc/htc_7010-1.4.0.fw reques
ted
[ 146.938943] usbcore: registered new interface driver ath9k_htc
[ 147.051422] usb 5-1.4: ath9k_htc: Transferred FW: ath9k_htc/htc_7010-1.4.0.fw
, size: 72812
[ 147.060165] usb 5-1.4: ath9k_htc: Unable to allocate URBs
[ 147.066080] usb 5-1.4: ath9k_htc: USB layer deinitialized
[ 153.176102] usb 5-1.4: USB disconnect, device number 7
now, here's the really strange thing: this issue does *NOT* occur if
the ath9k_htc 9271 dongle is plugged in as the very first device (but
we get additional problems) here's the sequences that i've tried so
far:
* plug in TP-Link 9271 dongle: works fine
* plug in Logitech dual-endpoint (hybrid usb-hid keyboard and usb-hid trackpad):
keyboard works, TRACKPAD DOES NOT
* unplug either device and re-plug them back in, result is:
[ 804.942464] usb 5-1: new high-speed USB device number 58 using musb-hdrc
[ 805.482464] usb 5-1: new high-speed USB device number 59 using musb-hdrc
[ 806.022463] usb 5-1: new high-speed USB device number 60 using musb-hdrc
[ 806.602464] usb 5-1: new high-speed USB device number 61 using musb-hdrc
[ 807.182479] usb 5-1: new high-speed USB device number 62 using musb-hdrc
if the hub is then unplugged it is no longer recognised. plugging in
any usb device directly into the usb port is also no longer
recognised.
second sequence attempted:
* plug in Logitech dual-endpoint device: works fine
* plug in TP-Link 9271 dongle: Unable to allocate URBs
* unplug both devices, plug something (anything) back in: new
high-speed number 58 59 60 61 62 .... one every second
third sequence attempted:
* plug in Logitech dual-endpoint device: works fine
* plug in ASIX88xxx USB-ETH dongle: works fine
* plug in *SECOND* ASIX88xx USB-ETH dongle: works fine
* plug in TP-Link 9271: wark, wark
in essence, then, it would seem as if the TP-Link 9271 is
destabilising the usb bus infrastructure.
any additional information needed, please do let me know.
