I'm attempting to use carl9170 in AP mode and I'm seeing some
interesting errors. When calling hostapd to initialize the AP, 10-50%
of the attempts will be unsuccessful and report the following:
Could not set interface wlan0 flags: Connection ieee80211 phy1: lost 7
command responses/traps! w:9 g:0
usb 1-1: restart device (8)
timed out
nl80211: Could not set interface 'wlan0' UP
nl80211 driver initialization failed.
rmdir[ctrl_interface]: No such file or directory
usb 1-1: firmware upload failed (-110).
usb 1-1: Failed to restart device (-110).
usb 1-1: reset high speed USB device number 2 using ehci-omap
usb 1-1: reset high speed USB device number 2 using ehci-omap
usb 1-1: driver API: 1.9.2 2011-01-22 [1-1]
usb 1-1: firmware API: 1.9.2 2010-12-25
usb 1-1: Atheros AR9170 is registered as 'phy2'
I'm seeing this error on the Beagleboard xM (Ubuntu 11.04 2.6.38) as
well as on a Lenovo x200 PC (Ubuntu 11.04 2.6.38). I've reproduced it
with 2.6.39 on the Beagleboard (not xM) as well. When initializing the
normal client mode, I've never seen a failure to "upload" the firmware
like this. It seems to be particular to the AP mode. Suggestions for
resolution are appreciated. I'm going to open up the carl9170 firmware
source and start trying to determine a possible cause there.
Thanks,
Brandt

Updated news, built a carl9170 firmware off the 1.9.4 tag and this issue
appears to have been resolved. I expect it was related to some of the
"timing" changes that appear to have been made.
Thanks,
Brandt
