Other Parts Discussed in Thread: TUSB9261
With disk IO activity on a particular model of embedded device I'm experiencing compatibility issues between the device and the TUSB9261, that I do not observe on my desktop on Linux or Windows.
I'm able to successfully mount a partition from this drive in Linux (kernel version 4.4).
When running any file operations the TUSB9261 locks up and requires a reset.
1. Is there a firmware/configuration option available as a work around?
2. Unrelated, is it possible to get the firmware flashing utility for Linux?
