1-Wire Busmaster / USB Hostadapter DS9490R / Kernel issue

Cleveres-Heim · July 28, 2018

Hi guys,

first of all I want to thank all of the users so far contributing to these armbian images. The images are extremely stable and my personally preffered platform for Smart Home installations.

Unfortunately started using the 1-Wire BUS I am experiencing issues with the current kernel. At least this is what syslog entries let me assume.

Everything seems fine for some hours or sometimes even days. Then suddenly (often at night) the USB Hostadapter seems to get disconnected and the system need to be rebooted completely to get 1-Wire to work again. I already searched the net a bit and found many users having those issues with several usb devices, not only 1-Wire. The syslog entries are always very similar and all deal with "ohci-platform" before usb devices stop to work.

This is my sylog from last night:

Jul 28 04:14:25 localhost kernel: [398581.169308] ohci-platform 1c14400.usb: frame counter not updating; disabled
Jul 28 04:14:25 localhost kernel: [398581.169321] ohci-platform 1c14400.usb: HC died; cleaning up

Jul 28 04:14:31 localhost OWFS[937]: DEFAULT: ow_reconnect.c:(70) Failed to reconnect DS9490 bus master!

Any idea how this can be fixed. Or is there a bug in armbian kernel?

Best regards,

Artur

Hi!

I have found additional information. There is a post in ubuntuforums.org (https://ubuntuforums.org/showthread.php?t=2342985&p=13655958#post13655958)

They are talking about "hid-quirks.c of the kernel source" and the fact, that some "usbhid devices need to be always polled to prevent a buffer overflow".

Any possibility to contribute idVendor and idProduct from the 1-Wire USB Hostadapter?
