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 so, I'll try to reproduce it by scanning. Till now I had no clue about the cause. Cheers, -- Antonio Quartulli ..each of us alone is worth nothing..

Normally if you use network manager, it will scan each 160 seconds or so. In this case you will get this warning lot more often. Probably it comes together: hight network traffic + channel scan + usb traffic of other devices on same bus. -- Regards, Oleksij ^ permalink raw reply [flat|nested] 7+ messages in thread
