I've been having trouble getting my Pinebook Pro's left-hand USB port, the large Type-A one with the blue interior and superspeed pins, to work at all. I can get power from it alright (though no data on whether negotiation is working yet), but nothing I plug into it enumerates or shows up in `lsusb`, nor does `dmesg` show any events. This applies to both USB-2.0-only devices, as well as those that support USB 3.0. The other USB ports - the Type-C one, and the 2.0 Type-A one on the right side, are both working just fine, so I'm suspecting the hardware here. I'm mainly posting this thread to ask if anyone else can confirm that their 3.0 port works, just so we can narrow it down to a spurious defect in my particular unit (one that I, confident with a soldering iron, might repair) or a more general design flaw or firmware bug that needs more professional attention.

So, does your left Type-A USB port work?

Noticing that the PBP emits a whine whenever video is playing.

The whine disappears shortly after the video is paused or stopped.

Anyone else noticing the same?

I'm posting this here because I just fixed an irritating issue on my Pinebook Pro and want others to be able to do the same if/when it affects them.

If you've put your Pinebook Pro to sleep and returned to it later, you may have noticed that there are sometimes things broken when it wakes back up. On mine, the keyboard layout modifications I've set using xmodmap (converting caps lock to a second escape, and the |\ key right beside left shift to be an additional left shift, since I'm used to the wider key provided on ANSI keyboards) all get reset back to defaults, and my trackpad stops responding to taps. Both of these were cramping my style enough that was just electing not to use suspend at all.

The solution to these problems is just to run two commands:

I measured the power usage over a day using the Mate power daemon. This is what it plotted.

It seems that charging via USB-C is almost as efficient as using an actual charger. The suspend one is weirder: it uses energy as much as a charger can put in the battery. I entered suspend by clicking on the power button and then selecting suspend on the pop up menu. Obviously something is not being properly powered down. This is with the default Debian image.

In my quest to fix my sound, I happened to notice in alsamixer a bunch of settings and two of which happened to be LDAC and RDAC... Seems like it uses 2 DACS, one for left channel and one for right channel. in the name of the sound card/board, the first 2 letters state "es". I wonder, if it uses 2 ESS dacs, anyone know which brand DAC's the PBP uses or have a good picture of the motherboard ? Thanks

For those of you using the headphone UART cable:

If you toggle the eMMC enable/disable switch by mistake your Pinebook Pro may not power on.

To resolve this toggle the eMMC switch back towards the hinge to enable eMMC. And then press the reset button. The device should now power on.

You will now find these instructions in the wiki.

Hello,

what is the exact size of the Pinebook Pro's Keys? I want to order ISO and then a set of these (https://www.amazon.de/Lacerto%C2%AE-14x1...160&sr=8-7) and then re-label the Keyboard to German. For this I need to know the exact key size.

Yours sincerely
Stefan

Seem to have a problem logging in today with Firefox (#70) on Apple iMac starting this afternoon in spite of working perfectly for ages up to this morning.

At some point this afternoon the [LOGIN] and [REGISTER] buttons appeared at the top of the page and clicking login takes me to the usual login box (pre-filled by browser but I have also tried retyping)

Clicking on the Login button returns me to the forum still not logged in but with a message 

"Authorization code mismatch. Are you accessing this function correctly? Please go back and try again."

On this same computer, using Chrome browser and the same login credentials, login is perfect. 

Any idea what is going on here?

Hi,

I've been tinkering with my PBP for the past few days now (mostly with the system monitor open). I'm happy enough with the current performance, but I've been wondering where the primary performance bottleneck lies in the PBP. Is it the eMMC interface? If so, I take it that purchasing an NVMe SSD would noticeably speed things up?

Hi,

Has anyone else noticed that MATE System Monitor shows seven CPU cores in Debian? CPU 7 never moves from 0.0% (I'm guessing because it doesn't exist).
