If've put up a list of things that need to be done still in the FreeBSD
USB stack. The list is _big_. I'll be adding things as they come up.
http://www.etla.net/~n_hibma/usb/usb.pl
A lot of the items are not that difficult to do and if you feel like
taking up a little project, start working on something and send
patches/source as you work through them. It might change the short term
priority list a bit to include your toy :-)
The Todo list is included below.

To Do list for the USB project:
Let meknow if you would like to participate in any way, or you have
done one of the items below!
- Short term priority list
- Finish off the import of the urio driver. Update the license
in rio500_usb.h.
- Finish the synchronisation with NetBSD
- Split umass into two parts: wire (BBB, CBI) and command
protocols
- Investigate panic on close of interrupt pipe with low frequency.
- Finally checkout the umodem driver and include it in the tree.
- USB base stack and general items.
- Fix/check suspend on UHCI and OHCI controllers, especially on
laptops.
- Use a kthread to handle the 'Done Queue'.
- OHCI connection problems
- Check out the manpages available. Add new ones where
appropriate.
- Generic driver should be available for all devices, not only for
the ones that nothing else attaches to.
- Possibility of locking pipes, interfaces & devices to make
sure no concurrent accesses are done (confusing a device, e.g.
e-shuttle USB)
- Implement poll/select for generic device. Idea: When select is
called for reading and no read is in progress a read for
MaxPacketSize with SHORT PACKET OK set is initiated. Select for
writing always succeeds.
- One shot transfers on interrupt pipes (needed for 'bulk' outs on
low speed devices for example).
- USB userland utility (usbcontrol)
- The word 'class' is used in usb.h. This is a problem for c++
compilers. Change the whole interface for usbdevs/usbd to something
sensible.
- Create a usbcontrol util combining all the functionality of
usb_dump.c, usbdevs and the usb*something* utility in NetBSD into one.
- USB Serial port driver (usio) driver (by Doug Ambrisko)
- Check out the version of sdcc that is in ports nowadays.
- Check out which dongles the usio driver works with
- Usio manpage.
- USB Mass Storage (umass) driver
- Check out the file system corruption problems under heavy load /
added load of a USB ethernet dongle.
- Check out support for ATAPI devices.
- Convert Read/Write_6 to Read/Write_10 in transform. This avoids
having to quirk every single UFI compliant device.
- USB Keyboards
- Keyboard in DDB debugger does not work.
- USB printer port support
- Bi-directional support
- Is the manual page up to date? Does it specify all the flags you
can set on the device minor number?
- Related:
- PCI/USB/PCCard/PCMCIA/other vendor, product and revision Id
matching code should be made generic, so that drivers can match in a
more generic way. The ID's should be collected into one location to
make the addition of new Id's more generic.
