I haven't really gotten around to the USB tuning yet. :/ In general we have many issues right now with USB:
- Not showing charge correctly in OS
- MTP / mass storage not working
- Speed tests, etc all in progress
- Possibly looking to add drivers for bluetooth adapters, etc once the kernel is stable.
...When complete this Kernel can seriously transform what the Fire is supposed to be and what is capable of ... not bad for a $200 piece of hardware.
Keep up the good work
