one question: i´ve connected the mpc via usb and copy 4 gb samples onto the 16 gb card, for 4 hours now, is that normal, that it is so slow?
Has anyone looked at what needs to be done, if anything, to support
USB 2.0 in the USB slave package? I noticed that only 1.1 is currently
supported based on the defines for supported version
#define USB_DEVICE_DESCRIPTOR_USB11_LO 0x10
#define USB_DEVICE_DESCRIPTOR_USB11_HI 0x01
Would supporting 2.0 be as simple as adding another define for 2.0? I
am not intimately familiar with USB, but if there is anything I can do
to help, I would be interested as we are looking at using eCos for an
internal board we are developing.
Thanks,

Yes, if your hardware is 2.0 compatible, you can simply indicate that in your device descriptor. (Yeah, we should probably add those constants to the USB header). If it's a Full Speed device, that's probably all you need to do. If it's a High Speed device you may have a little more work to do to implement and/or debug the high speed enumeration. I don't believe that any of the existing USB device drivers are for high speed devices, so there may not be any implementation to negotiate into high speed.

Hard drives have the benefit of providing tons of storage space. They have their downfalls though:
1) The moving components use a lot of power and generate a lot of heat
2) The Moving parts are going to fail eventually, Laptop hard drives especially
3) They are sensitive to shock/movement (IE: Banging on your Pads)
