Hi,
I am experiencing severe USB stability issues on my Odyssey X86J4125; ports keep disconnecting and the system needs to be reset. Both USB3 and USB2 are affected, although the latter appears to be more stable (i.e, can run for weeks w/o issue, presumably due to the lower 480Mbit/s bandwidth on USB2). Equipment connected to USB3 however will only work for a few minutes. The affected equipment has been tested on an identical OS running the same versions, and cable.
This started being noticable with an external storage system, connected via USB3 directly to the front USB3 (A) port. I have not previously used the Odyssey for this (my 2nd, older system referenced above, was the primary storage system until now)
I have have tried different cables – 2x USB-A to USB-B (the storage unit has a USB-B/host connector) and 1x USB-C to USB-B – using the USB-C input on the front (connecting to the same USB-B port on the storage system – an IcyBox RAID.
The front USB-C port behaves the same–presumably as it uses the same bus as the USB-A.
When this happens the port is effectively dead. USB2 works better, but this also occurred when it was connected to a USB2 port in the back.
Example kernel errors when this occurs (note: many different kernels have also been tried, including the exact same version being used on a different system where the same storage system works perfectly over USB3 (running for months and years). The issue appears to be specific to the Odyssey X86 – either bandwidth/voltage, USB controller chip or BIOS issue.
The behaviour is repeatable, and consistently happens within 20 minutes of disk i/o. Rebooting + reverting to a USB2 port fixes the issue, and it can then run for days – even weeks – until a similar USB port hang happens.
And to clarify: no USB hubs or any other equipment is connected. Issue has also been seen with USB mice connected to the USB3 port (laggy, or unresponsive. Fixed by reconnecting, or moving to a USB2 port)
