[ath9k-devel] EOMA68-A20 (allwinner sunxi a20) 4.7.0-rc2 ath9k_htc "ath9k_htc: Unable to allocate URBs" issue

[lkcl .]

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

[  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.

oo that's interesting..  i had to unplug the ath9k_htc because these
kept streaming up-screen, here's the setup:

* plug in USB3 powered hub into OTG port (set up as USB2 Host)
* plug in USB2 *unpowered* hub into 1 of USB3 powered hub ports
* plug in two ASIX88xx dongles into USB3 powered hub ports
* plug in ath9k_htc tp-link 9271 dongle into *USB2 unpowered* hub port
* unplug 9271 to stop messages going mad

 same massive set of continuous streaming of BOGUS urb if:

 * USB2 unpowered hub is plugged into OTG Host
 * USB3 powered hub is plugged into USB2 hub
 * 9271 dongle (no other devices) is plugged into USB3 host

hmmm i suspect the unpowered Genesys Logic USB2 hub more than
anything, but the continuous list of messages isn't helping... :)

In case of:
[  147.060165] usb 5-1.4: ath9k_htc: Unable to allocate URBs
you are out of bandwidth limit of you usb root hub.

Any research in this direction are welcome.

In case of:
[   75.816339] usb 5-1.4.2: BOGUS urb xfer, pipe 1 != type 3
the adapter was started in USB 1.0 mode (which is present, but never
tested - so, not supported.). Why it is in USB1 mode - no idea, but it
is already second time i have seen it.

Support for USB1 mode seems to be welcome too.

 *bandwidth* limit?!?!  bizarre.  but this is a USB3 hub plugged into
a USB2 port, and people plug these in directly into USB2 powered hubs
no problem with other devices (i just don't have one available right
now).

 alright i'll take a look around.

hm... take my words back

i reviewed the code, "ath9k_htc: Unable to allocate URBs" may come if
there is not enough RAM or it is too fragmented. Some other reasons
can be too, but current code is not verbose enough to provide mode
information.

 eenterestiiing... and this is on a system with 1gb RAM, embedded
system, where i'd started up a full desktop environment.

 okay so i should put in a few more printk's at various points, stop
xfce4, and generally try narrowing things down a bit.
