Hi,
I'm still debugging my hcd. I still have some issues, and one of them
is related to urb->hcpriv usage. Following explain how I use it:
urb->hcpriv keeps a pointer on a structure which gives an internal
description of the urb for my hcd. This field is initialized in
"hcd->urb_enqueue" method. Then it's set to NULL just before giving
back the urb to the driver through "usb_hcd_giveback_urb".
But sometime this field is NULL when starting an URB transfer ! That's
normally impossible since _all_ URBs submitted to an HCD use
"hcd->urb_enqueue", isn't it ?
Could someone help me on this point ?
Thanks
