Even if you don't have these problems, it's also useful to determine it doesn't break anything new. We would like to enable that by default soon.
If you are suffering from lost USB packets:
will help with interrupt latency. We believe the sync_after_dma is safe, and will be enabled by default soon.
The missing_status is the one that gives the most benefit, but unfortunately doesn't work with all sdcards.
We're still looking into a better solution.
Always wise to backup your sdcard before trying something like this, just in case.
We believe there is an additional reason for packet loss due to mixed high/low speed devices and split transactions.
No fix for that yet, gsh is still investigating.
