* Rearrange some basic setup to be more towards the top of the function,
so we have less things to tear down upon failures.
* Don't double-initialize qwtrb0 of the Setup Stage (no functional change.)
* Rework Data Stage initialization considerably:
- TD_SIZE refers to the number of remaining TRBs in this TD. As we only
use 1 TRB for the Data Stage TD at present, this should be 0, not 1.
- Actually copy data for outbound transfers. (This code does get hit,
so I'm not sure how it wasn't a problem previously.)
* Initialize the first quadbit of the Status Stage. (Potentially a
functional change.)
* Set the TRB_3_DIR bit on the Status Stage correctly as per the spec.
(See inline comment.)
Device initialization seems to behave much more smoothly now; at least on
my hardware, the "error Parameter" doesn't happen anymore, and of course
anything depending on outbound Control transfers will now work correctly.
I now get much better speeds from usb_disk, but I still see usb_hid stalls
after this patch.
Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!

Contributing documentation
The main piece of documentation that still needs work are the API docs (found
in the tree at docs/user). Just find an undocumented class, write
documentation for it, and submit a patch.
