I've looked into this and unfortunately it looks like a hardware failure to me. Can you try the vendor driver (https://github.com/porjo/mt7601) and report if it works?

helium78 · 2015-04-08T21:50:49Z

I don't have problems using USB hard drives at these ports. What kernels can I use with the vendor driver? Are there any Linux live systems that I can test it with an old kernel and the vendor driver?

kuba-moo · 2015-04-09T06:31:17Z

I meant that the WiFi dongle can be broken, especially if it's one of the cheap "black and red" no-names.

I gave you a link to @projo's version of the vendor driver because it should work with any kernel, new or old. If it doesn't let me know I will fix it for you.

cusspvz · 2015-05-19T19:48:37Z

Same here with 15.04, running inside a VB vm on a Macbook Pro retina.

kuba-moo · 2015-05-19T22:14:04Z

@cusspvz Logs or didn't happen. Also please test if @projo's driver works as I suggested above.

cusspvz · 2015-05-20T12:19:11Z

@projo driver is working, with some flaws.
Didn't posted logs since they were equal to the ones provided by @helium78 .

mt7601u 1-3:1.0: Vendor request req:02 off:x0506 failed:-110 keeps showing up on syslog.

kuba-moo · 2015-06-05T16:22:17Z

@helium78 @cusspvz After a lot of thinking I might have an idea - can you test the debug branch?

rrthomas · 2015-06-07T20:43:09Z

I'm still getting these crash logs with the latest debug branch; is there any other information I can supply?

kuba-moo · 2015-06-07T21:19:09Z

In @helium78's case the device got completely mad for reason which is not clear to me. Your device @rrthomas just has incomplete eeprom and everything is fine, I should ignore the values and use zeros instead. @cusspvz didn't feel it's appropriate to put logs in his error report so I have no idea what his problem was.

Please do not assume that if something looks like "the same crash" to your untrained eyes, it's actually the same problem ;)

cusspvz · 2015-06-07T21:32:22Z

@kuba-moo didn't tested yet since i have to install ubuntu again on VirtualBox. 😞
But ASAP i would do that (on the next days i'm busy as hell).

I can advance to you that my VM crashed every time on about 3 minutes after I loaded the driver.

rrthomas · 2015-06-07T21:38:53Z

Sorry, when you said in issue #18 "I think we may be dealing with two separate issues here - the xHCI xhci_drop_endpoint called with disabled ep which I've already been asked about" I thought that referred to this issue.

q4a · 2015-07-07T04:47:53Z

Ubuntu 15.04 works fine:
$ uname -a
Linux amd 3.19.0-22-generic #22-Ubuntu SMP Tue Jun 16 17:15:15 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
$ lsmod|grep mt76
mt7601u 98304 0
mac80211 724992 1 mt7601u
cfg80211 540672 2 mac80211,mt7601u

But i need to run for wifi:
sudo rfkill unblock wifi
sudo wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/example.conf
sudo dhcpcd wlan0

kuba-moo · 2015-07-08T08:34:19Z

@q4a Sounds like a configuration issue with higher layer software. If wpa_supplicant works fine the driver is OK.
