problem with udoo quad and wireless connection

[tuxx]

Hi all,

I have been experimenting for days with Udoo quad and wireless for some days now. I am using it in order to get music from my linux nas and play my flac files with mpd and a usb dac.

At first I heard some drops and running dmesg I saw a ralink related error:

$this->bbcode_second_pass_quote('', '[') 2417.288971] ieee80211 phy0: rt2800usb_txdone: Warning - Data pending for entry 8 in queue 2

I am now testing another "fix" for this module:

$this->bbcode_second_pass_code('', 'options rt2800usb nohwcrypt=1')

I will come back with my results.

It seems that the kernel.org upstream rt28700usb firmware is outdated (v 0.29). I downloaded latest driver from:

http://www.mediatek.com/en/downloads/

and I replaced:

/lib/firmware/rt2870.bin

with the binary from the downloaded driver. dmesg now shows:

$this->bbcode_second_pass_quote('', '[') 7.452403] ieee80211 phy0: rt2x00lib_request_firmware: Info - Loading firmware file 'rt2870.bin'
[ 7.464411] ieee80211 phy0: rt2x00lib_request_firmware: Info - Firmware detected - version: 0.33

After many days with the new firmware, I confirm that the situation is much better.

After of 12 hours of uptime and reproducing files from the NAS, I got the error only three times.

Does anyone know if this is actually data loss or not, because I am not able to hear any problem anymore when it happens:

$this->bbcode_second_pass_code('', '[ 2417.288971] ieee80211 phy0: rt2800usb_txdone: Warning - Data pending for entry 8 in queue 2')
