USB for OS/2 and eCS

This should become the home for about all source code related to USB on OS/2 and eCS, namely:

• USB UHCI, OHCI and EHCI (at least as much as possible of that stuff)
• libusb, mainly used for Unix-like apps
• USBCFG (ask the author, not sure if this is OSS)
• USB CDROM stuff (search for USB on hobbes)
• USB MSD clones
• USBMOUNTD (search hobbes)
• ... whatever we forgot

A more detailed list of stuff can be found in the ​netlabs.org Wiki.

We hope that we can fix the USB mess we have right now and get versions that can be used by any other developer easily.
