Title: Avalon hash rate keeps resetting, USB hub issues? Post by: TwinTurbo on August 18, 2013, 12:06:43 PM Hi All,
So I am seeing this appear over and over in the System Log, but my other Avalon boxes have no such problem: Sun Aug 18 11:48:49 2013 auth.info kernel: [ 558.900000] usb 1-1: USB disconnect, device number 36 Sun Aug 18 11:48:49 2013 auth.info kernel: [ 558.910000] usb 1-1.1: USB disconnect, device number 37 Sun Aug 18 11:48:50 2013 auth.info kernel: [ 559.210000] usb 1-1: new high-speed USB device number 38 using ehci-platform Sun Aug 18 11:48:50 2013 auth.info kernel: [ 559.380000] hub 1-1:1.0: USB hub found Sun Aug 18 11:48:50 2013 auth.info kernel: [ 559.380000] hub 1-1:1.0: 2 ports detected Sun Aug 18 11:48:50 2013 auth.info kernel: [ 559.660000] usb 1-1.1: new full-speed USB device number 39 using ehci-platform Sun Aug 18 11:48:50 2013 auth.info kernel: [ 559.810000] ftdi_sio 1-1.1:1.0: FTDI USB Serial Device converter detected Sun Aug 18 11:48:50 2013 auth.info kernel: [ 559.820000] usb 1-1.1: Detected FT232RL Sun Aug 18 11:48:50 2013 auth.info kernel: [ 559.820000] usb 1-1.1: Number of endpoints 2 Sun Aug 18 11:48:50 2013 auth.info kernel: [ 559.820000] usb 1-1.1: Endpoint 1 MaxPacketSize 16384 Sun Aug 18 11:48:50 2013 auth.info kernel: [ 559.830000] usb 1-1.1: Endpoint 2 MaxPacketSize 16384 Sun Aug 18 11:48:50 2013 auth.info kernel: [ 559.830000] usb 1-1.1: Setting MaxPacketSize 64 Sun Aug 18 11:48:50 2013 auth.info kernel: [ 559.840000] usb 1-1.1: FTDI USB Serial Device converter now attached to ttyUSB0 Sun Aug 18 11:48:51 2013 auth.info kernel: [ 560.970000] ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0 Sun Aug 18 11:48:51 2013 auth.info kernel: [ 560.990000] ftdi_sio 1-1.1:1.0: device disconnected Sun Aug 18 11:49:12 2013 auth.info kernel: [ 581.570000] usb 1-1: USB disconnect, device number 38 Sun Aug 18 11:49:12 2013 auth.info kernel: [ 581.570000] usb 1-1.1: USB disconnect, device number 39 Sun Aug 18 11:49:12 2013 auth.info kernel: [ 581.880000] usb 1-1: new high-speed USB device number 40 using ehci-platform Sun Aug 18 11:49:12 2013 auth.info kernel: [ 582.050000] hub 1-1:1.0: USB hub found Sun Aug 18 11:49:12 2013 auth.info kernel: [ 582.050000] hub 1-1:1.0: 2 ports detected I noticed that my box's hash rate started resetting to 0 MH/s and then climbing back up to 70 or so. It did this once before right when I first got my Avalon and I couldn't figure out why. I moved the box around a bit and the issue went away ever since. Fast forward a month: I had to re-arrange some hardware recently and my Avalon ran fine for a day, then stopped hashing last night. I restarted it and then it ran fine for several hours. When I log in, I see the above in the logs, the 5 second average hash rate climbs up to the 70 or so GH/s then resets to 0 and repeats. It seems to me that maybe I have a bad hub connection judging by the logs. Currently I have it set to run at 300 MHz, but it has no problems hitting 345 MHz and ran for a month just fine before I moved it around. WiFi is disabled, etc. Anyone else experienced problems like this? How did you resolve it? Title: Re: Avalon hash rate keeps resetting, USB hub issues?

What should I look at connection wise to make sure seems ok. Title: Re: Avalon hash rate keeps resetting, USB hub issues?
