Re: PCTV400e - dvb-usb: bulk message failed / ttusb2: i2c transfer failed / PPC

[darav@xxxxxx]

Hello Mr. Boettcher,
Hello ML,

unfortunatly I didn't get it working - yet :)

But I came a little bit further:
I seems that in linux kernel at drivers/usb/core/message.c in  
function usb_bulk_msg() the ep is null:	
        if (!ep)
            return -EINVAL; // <-- -22
The ep is determined by
  ep = (usb_pipein(pipe) ? usb_dev->ep_in : usb_dev->ep_out)
                        [usb_pipeendpoint(pipe)];
The value of pipe seems ok (nearly the same as on my x86).

So the actlen from v4l-dvb/linux/drivers/media/dvb/dvb-usb/dvb-usb- 
urb.c in function dvb_usb_generic_rw
       if (ret)
                err("bulk message failed: %d (%d/%d)",ret,wlen,actlen);
isn't even set.
That's where "dvb-usb: bulk message failed: -22 (8/164598 = actlen)"  
came from.
So ep seems the problem - not actlen.

I tried to debug it further but I didn't see anything obviously.
I enable deb_xfer and debug_dump which gives me the following:

[17179824.984000] drivers/usb/core/inode.c: creating file '004'

So the commands (>>>) are ok so far, except on my ppc the following  
commands are shown (not on x86) - where each of them fail:
[  241.796125] >>> aa 0c 31 04 10 01 00 40
[  241.796153] >>> aa 0d 31 04 1d 01 01 00
[  241.796175] >>> aa 0e 31 05 1c 02 00 00 08
These are the same command sent earlier - but in reverse order:
[  241.796175] >>> aa 0e 31 05 1c 02 00 00 08
[  227.795068] >>> aa 07 31 04 1d 01 01 00
[  227.808629] >>> aa 09 31 04 10 01 00 40

Why are these commands sent? Is this is a try to reinit the device?  
Or doesn't the driver know, that it's already initilized?


The results (<<<) are indeed different, but I didn't see a endian  
problem there: the output only differs in a few bytes - the end of  
the buffer is always the same - but different on each machine.
But looks good to me - maybe you can see something more?

Why could ep being null, which seems the main problem to me?
Could you please give me some hints where to look next?

If it would help you to get access to a ppc machine - we could  
arrange it.

Many thanks in advance!
