Dear all:
I have some questions about host driver:
1. why we use *dummy = *qtd instead of memcpy(dummy,qtd,sizeof(struct ehci_qtd)?
Since *dummy = *qtd tried to copy the content of qtd which points
to to where dummy pointed to, right?
2. why we set a limitation about usbdevfs_urb, MAX_USBFS_BUFFER_SIZE (16K)?
we don't do so with kernel urb, and why the size is 16k instead of
20k, the limitation of an qtd?
appreciate your help in advance,
miloody
