Hi,
thank you.
please do some tests for me.
1. run wireless adapter without other devices on this bus.
Bus 002 Device 003: ID 0cf3:9271 Atheros Communications, Inc. AR9271
802.11n
Bus 002 Device 011: ID 03f0:8607 Hewlett-Packard Optical Mobile Mouse
Bus 002 Device 005: ID 0403:6001 Future Technology Devices
International, Ltd
FT232 USB-Serial (UART) IC
Bus 002 Device 006: ID 413c:8187 Dell Computer Corp. DW375 Bluetooth
Module
probably Bluetooth can't be removed, so disable it by software.
2. if this warning disappear, plug them back and rung kernel with
attached patch. I wont to see if this warning related to channel scan.
3. try latest wireless-next kernel
https://git.kernel.org/cgit/linux/kernel/git/linville/wireless-next.git/
there are some patches which will affect usb communication, this will be
visible on your hardware, in good or bad way. Will see how it performs
in your situation.
I assume this warning is related to usb bandwidth. Since we use BULK
transfer, we will get only rest of it. If other devices use ISO or
Interrupt, They well have priority.
I'm not using the Intel card listed in lspci. (the iwldvm module is
loaded but
the interface is down).
Cheers,

Hello list,
I ma connected to my WPA2-PSK protected network and from time to
time I get the
following warning in dmesg. I don't experience any malfunctionng but
I thought
it was worth reporting. My kernel version is linux-3.10.10. I
remember I've seen
this warning also with previous versions.
The device I use is a TP-LINK TL-WN721N.
