I forgot to mention: I switched boards this time - my previous logs
were from a Meson8m2 board
to rule out that the board itself is faulty I switched to an Odroid-C1
(Meson8b) this time -> there's a 4-port USB hub hard-wired on the
Odroid-C1 which you can see in the kernel logs (just in case you are
wondering)

 Hello,

 I was a bit surprised to see that hot-plugging USB devices on Amlogic
 Meson8b (for example: Odroid-C1) is broken.
 to be fair: I *think* it worked before, but I cannot guarantee it nor
 can I say when it broke

 all examples below are from an Odroid-C1 board with Amlogic Meson8b (S805) 
 SoC.
 this connects a (fixed, soldered down) 4-port USB hub to the dwc2
 controller (which is in "host" mode)

 during boot I see:
 [1.651687] dwc2 c90c.usb: c90c.usb supply vusb_d not

 if a USB device is plugged into one of the four USB ports during boot
 then it is detected automatically.
 if I plug in devices later they are not detected automatically (I have
 to run "lsusb -v" due to some reason, then hot-plugged devices are
 being detected)
 un-plugging USB devices is recognized instantly (no "lsusb" trickery
 is required)

 is this a known issue? how can I help debugging?
 any help is appreciated!

 below is the output of all dwc2 debugfs files.

dwc2 (on Meson8b) doesn't detect "hot-plugged" USB devices

2018-05-06 Thread Martin Blumenstingl 
Hello,

I was a bit surprised to see that hot-plugging USB devices on Amlogic
Meson8b (for example: Odroid-C1) is broken.
to be fair: I *think* it worked before, but I cannot guarantee it nor
can I say when it broke

all examples below are from an Odroid-C1 board with Amlogic Meson8b (S805) SoC.
this connects a (fixed, soldered down) 4-port USB hub to the dwc2
controller (which is in "host" mode)

during boot I see:
[1.651687] dwc2 c90c.usb: c90c.usb supply vusb_d not
found, using dummy regulator
[1.654434] dwc2 c90c.usb: c90c.usb supply vusb_a not
found, using dummy regulator
[1.732374] dwc2 c90c.usb: dwc2_check_params: Invalid parameter lpm=1
[1.733526] dwc2 c90c.usb: dwc2_check_params: Invalid parameter
lpm_clock_gating=1
[1.741427] dwc2 c90c.usb: dwc2_check_params: Invalid parameter besl=1
[1.748305] dwc2 c90c.usb: dwc2_check_params: Invalid parameter
hird_threshold_en=1
[1.756491] dwc2 c90c.usb: DWC OTG Controller
[1.760993] dwc2 c90c.usb: new USB bus registered, assigned bus number 1
[1.768046] dwc2 c90c.usb: irq 24, io mem 0xc90c
[1.773947] hub 1-0:1.0: USB hub found
[1.777063] hub 1-0:1.0: 1 port detected
...
[2.212432] usb 1-1: new high-speed USB device number 2 using dwc2
[2.464742] hub 1-1:1.0: USB hub found
[2.465118] hub 1-1:1.0: 4 ports detected

if a USB device is plugged into one of the four USB ports during boot
then it is detected automatically.
if I plug in devices later they are not detected automatically (I have
to run "lsusb -v" due to some reason, then hot-plugged devices are
being detected)
un-plugging USB devices is recognized instantly (no "lsusb" trickery
is required)

is this a known issue? how can I help debugging?
any help is appreciated!

below is the output of all dwc2 debugfs files.

Martin
