New Revision: 51864
URL: http://svn.reactos.org/svn/reactos?rev=51864&view=rev
Log:
[USBOHCI]
- Start implementing control transfers
- Move initialization of usb queue after the bulk / control head endpoints have been
created
- Add interface functions to retrieve bulk / control head endpoint descriptors
- Add macros for setting transfer descriptors field (taken from Haiku)
- Partly implement IUSBQueue::AddUSBRequest for control / bulk transfers
- Create endpoint descriptor for control request and link setup descriptor to it
- Link setup descriptors to data descriptor / status descriptor
- WIP (needs fixes)
