Hi,
I have a HP DL380 Gen9 Server which is connected to a 1-Wire sensor network via USB:
Server -> USB-HUB (EX-SYS 1178) -> USB to I2C adapter -> DS2482-800 (I2C to 1-Wire adapter)
Except the Server, this setup was working for over 5 years with Dell 2950 without issues. I have upgraded the server from Dell to HP about 50days from today. The difference between Dell and HP: USB 2.0 (ehci) and USB 3.0 (xhci).
The USB connection stopped working the first time after 45days. The second time today after 5day. The message always starts like this:
| Code: |
[496204.762154] usb 2-11: USB disconnect, device number 3
[496204.762157] usb 2-11.1: USB disconnect, device number 5
|
The device behind 2-11.1 is the USB to I2C adapter. The odd part: even if I change ports on the USB-HUB, the server does no longer recognize the change and it will no longer communicate with the 1-Wire network.
Today I have tried to "grab" USB from the server by using it with Virtualbox and

After stopping the virtual machine, I can access the 1-Wire network (as the whole USB subsystem has been reset).
I am using Kernel 4.9.16-gentoo; system is hardended/amd64 profile.
Long story, short question:
- Is this issue a software or hardware problem?
- What can I do to have a stable USB connection?
Thank for a helping hand.
