[Replicant] i9300: USB issue => No adb

Fri Sep 22 19:39:10 UTC 2017

Hi,

I'm not sure where the problem comes from, so I prefer asking on the
mailing list rather than doing a bug report.

With the i3900, I am able to use heimdall to reflash the recovery:

Here It successfully flashed the new recovery.

Here's the heimdall version I have:
> # pacman -sS heimdall
> community/heimdall 1.4.2-1 [installed]
>     Tool suite used to flash firmware (aka ROMs) onto Samsung mobile
> devices

Then after booting, I look again at dmesg:
> [ 4447.083519] usb 1-1: reset high-speed USB device number 3 using
> ehci-pci [ 4447.222649] usb 1-1: USB disconnect, device number 3
> [ 4447.343381] usb 1-1: new high-speed USB device number 4 using
> ehci-pci [ 4454.678355] usb 1-1: USB disconnect, device number 4
> [ 4477.980152] usb 1-1: new high-speed USB device number 5 using
> ehci-pci
and it tells me that there are new devices on the USB bus, with the
device number increasing.

After that I try to connect to it trough adb:
> # adb shell
> * daemon not running. starting it now at tcp:5037 *
> * daemon started successfully *
> error: no devices/emulators found
and it founds no device.

And after that, my laptop's kernel sees many new USB devices, and the
number is still increasing constantly:
> [ 4660.770129] usb 1-1: new high-speed USB device number 10 using
> ehci-pci [ 4661.133406] usb 1-1: reset high-speed USB device number
> 10 using ehci-pci [ 4661.271740] usb 1-1: USB disconnect, device
> number 10 [ 4661.526741] usb 1-1: new high-speed USB device number 11
> using ehci-pci [ 4661.890054] usb 1-1: reset high-speed USB device
> number 11 using ehci-pci [ 4662.028246] usb 1-1: USB disconnect,
> device number 11 [ 4662.280105] usb 1-1: new high-speed USB device
> number 12 using ehci-pci [ 4662.653407] usb 1-1: reset high-speed USB
> device number 12 using ehci-pci [ 4662.791001] usb 1-1: USB
> disconnect, device number 12

For instance after a some time I get:
> [ 4865.423432] usb 1-1: new high-speed USB device number 27 using
> ehci-pci [ 4865.793348] usb 1-1: reset high-speed USB device number
> 27 using ehci-pci [ 4865.931646] usb 1-1: USB disconnect, device
> number 27 [ 4866.186783] usb 1-1: new high-speed USB device number 28
> using ehci-pci [ 4866.550053] usb 1-1: reset high-speed USB device
> number 28 using ehci-pci [ 4866.687673] usb 1-1: USB disconnect,
> device number 28

After a reboot I then get some:
> [ 5070.283389] usb 1-1: reset high-speed USB device number 13 using
> ehci-pci [ 5070.425048] usb 1-1: can't restore configuration #1
> (error=-71) [ 5070.425283] usb 1-1: USB disconnect, device number 13
> [ 5070.680067] usb 1-1: new high-speed USB device number 14 using
> ehci-pci [ 5071.043499] usb 1-1: reset high-speed USB device number
> 14 using ehci-pci [ 5071.191739] usb 1-1: can't restore configuration
> #1 (error=-71) [ 5071.191990] usb 1-1: USB disconnect, device number
> 14 [ 5071.443423] usb 1-1: new high-speed USB device number 15 using
> ehci-pci [ 5071.556739] usb 1-1: device descriptor read/64, error -32
> [ 5071.776704] usb 1-1: device descriptor read/64, error -32
> [ 5071.996735] usb 1-1: new high-speed USB device number 16 using
> ehci-pci [ 5072.110085] usb 1-1: device descriptor read/64, error -32
> [ 5072.330093] usb 1-1: device descriptor read/64, error -32

Questions:
- Are other people getting similar behavior?
- Can it be related to USB power management? I've deactivated USB bus
  power management but it didn't fix the issue.

I can also try to deactivate more power management and/or try other
computers to try to narrow down the issue.
