Greg,
In my program, I have following lines:
struct usbdevfs_urb *pURB;
pURB->type = USBDEVFS_URB_TYPE_BULK;
pURB->endpoint = endpoint;
pURB->buffer = pBuffer;
pURB->buffer_length = iBufferLen;
pURB->signr = signal;
pURB->number_of_packets = iNumPackets;
pURB->usercontext = pUserContext;
pURB->flags = USBDEVFS_URB_QUEUE_BULK;
iResult = ioctl(m_fd,USBDEVFS_SUBMITURB,pURB);
I don't know why in the devio.c, proc_submiturb() will return with
-EINVAL at this if statement: If ( uurb.flags &
~(USBDEVFS_URB_ISO_ASAP|USBDEVFS_SHORT_NOT_OK|URB_NOT_FSRB|URB_ZERO_PACK
ET)) { Return EINVAL; }
Does Fedroa take out the support of USBDEVFS_URB_QUEUE_BULK? If yes,
what is alternative way to use it? It was working on 2.4 kernel.
I can change the pURB->flags to be USBDEVFS_URB_ISO_ASAP to make the
program go further, but the pURB->type (USBDEVFS_URB_TYPE_BULK) will
cause the op->submit_urb() to return errno 22 in the urb.c:
usb_submit_urb().
Do you have any clue?
Thanks
tclan

It has been called "usbfs" for over 2 years. That also works on 2.4 and
I think on 2.2.

Are you sure you have a hid device attached? Why would you need to
create the node, it should already be there if you have a static /dev,
or if you use udev.
thanks,
