unplug your USB-GPS temporarily from USB and do

lsusb

as pi user

With the usb-gps unplugged:

First lsusb with the usb-gps unplugged (the pi rebooted after unplugging it). Second lsusb with the usb-gps connected - AND NOW IT SHOWS IN SERIAL!?!

Now keep it plugged into USB and reboot. 
What are the results after that?

It's still there after reboot:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

And still shows up in Serial as ttyUSB0. This is good.

But: when I repeat the steps: disconnect usb-ports, reboot, connect my externally powered usb (3.0)-hub and lsusb :

Bus 002 Device 005: ID 2109:0817 VIA Labs, Inc. USB3.0 Hub             
Bus 002 Device 004: ID 2109:0817 VIA Labs, Inc. USB3.0 Hub

Bus 002 Device 002: ID 0781:5583 SanDisk Corp. Ultra Fit
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Serial is blank again. The connection seem possible from SerialK though:

I have similar problem but it might also be something different.

I used to have a Teensy device connected on a USB port of the Raspberry Pi with OpenPlotter & SignalK. Everything was working ok.
I had to change the Teensy device for a new one and since then, the USB device is partially detected. The behavior is this:
After a reboot of the RPI, the command lsusb return the following line, which is good: "Bus 001 Device 025: ID 16c0:0483 Van Ooijen Technische Informatica Teensyduino Serial"
In signalK/Server/DataConnections, I have defined the following parameter which are the same as the other Teensy device: NMEA2000 type, Actisense NGT-1 (canboatjs) . The serial port will show me /dev/serial/by-id/usb-Teensyduino_USB_Serial_11568930-if00, which I select and then reboot signalk.
After the reboot, I see in signalK dashboard that the Teensy get connected for a few seconds and right after I get the following message "EIO: i/o error, writeError:"
Sometime, if I try reselect the USB device in the signalK/Server/DataConnections, I get the message "No such file or directory, cannot open /dev/serial/by-id/usb-Teensyduino_..." and the device is no longer listed by the linux command lsusb
The OpenPlotter Setting System log gives me
Sep 30 11:52:53 openplotter kernel: [ 204.768808] usb 1-1.4: USB disconnect, device number 6

Sep 30 11:52:54 openplotter kernel: [ 205.221828] cdc_acm 1-1.4:1.0: ttyACM0: USB ACM device

When the Teensy is visible in the lsusb, I'm able to execute the arduino-cli to reprogram the Teensy via the USB cable so I don't suspect the USB cable, nor the USP port on the RPI.

Is it possible that the RPI OS or OpenPlotter/SignalK still expect the old Teensy device? It is not possible to put back the old Teensy for testing.
Any advice how to fix this?

---

I did other tests and every time I change the serial path signalK/Server/DataConnections for something that I can see with the command "ls -l /dev/serial", this path disappeer after the reboot of signalK; it looks like signalK is screwing up the USB device in /dev
My version of signalK is 1.45.0

[ptalbot]

I found the source of the problem, which is on my side; the listening program on the other end of the USB cable crashed and stopped listening so SignalK stopped seeing my device.

Hi fellows,
Same issue when trying to set a new fresh V3 system : The Rpi sees the newly inserted GPS in lsusb, but SERIAL only displays a 'HUB' as device deyected !!!
"ttyACM0/1546/01a8//VL805 USB 3.0 Host ControllerVIA Technologies. Inc.

Is it a 'SERIAL' bug and How to solve ?

I would try this to debug:

- is your GPS device detected without the HUB?

- Connect just 1 device at the same time to see if you have power issues

- Is your usb hub auto-powered?

- Have you tried another hub?

HI All .

I have noticed the following issue with SERIAL application : it does no longer displays the proper device name e.g. :

• in OP V3.0 : "VL 805 USB 3.0 Host controller ..."
  
• while in  OP V2.9 : "[u-blox 8] U-Blox-AG
  

for the same physical USB network .
This  will bring in some confusion ... as the only way to pick up the proper device is its (random) device/dev name : ttyACM0 (or 1, or ...)
SERIAL is there to remove this confusion, isn't it ?
