USB Mass Storage

Moin.

Since I have signed for the USB Mass Storage bounty, I started to toy with the USB manuals, AROS' USB stack and Efika. During my coding evening it suddenly turned out, that I've lost the bits and pieces of AROS USB code which were responsible for Bulk transfers. Funny. They were there a very long time ago, among my sources, now they were gone.

Whatever. I've added the bulk transfer support to USB stack implemented it in both OHCI and UHCI driver (the support for UHCI will follow shortly) and wrote the first bits and pieces of mass storage class. Here's the result:

[USB] USB::NewDevice()
[USB] Trying external class "hid.hidd"
[USB] Trying external class "storage.hidd"
[MSS] MatchCLID(0x8ed55, 0x89d74)
[MSS] UDCLASS_IN_INTERFACE OK. Checking interface 0
[MSS] iface 0 @ 0x89d7d class 8 subclass 6 protocol 80
[MSS] Interface may be handled by Mass Storage Class
[MSS] Lucky you. The device supports Bulk Only transport
[MSS] Protocol used: SCSI complete
[MSS] Pick me! Pick me! Pick me! I can handle it!
