[linux-dvb] af9015 problem on fedora rawhide 9.93 with 2.6.27x kernel

[Thomas]

Hi List,


since fedora use 2.6.27 kernels this
is all what happens when i plug in the stick:

Nov 11 13:24:56 thomas-lt kernel: usb 2-6: new high speed USB device using ehci_hcd and address 3
Nov 11 13:24:57 thomas-lt kernel: usb 2-6: configuration #1 chosen from 1 choice
Nov 11 13:24:57 thomas-lt kernel: Afatech DVB-T 2: Fixing fullspeed to highspeed interval: 16 -> 8
Nov 11 13:24:57 thomas-lt kernel: input: Afatech DVB-T 2 as /devices/pci0000:00/0000:00:1d.7/usb2/2-6/2-6:1.1/input/input9

Nov 11 13:24:57 thomas-lt kernel: usb 2-6: SerialNumber: 010101010600001
Nov 11 13:24:57 thomas-lt kernel: dvb-usb: found a 'Afatech AF9015 DVB-T USB2.0 stick' in cold state, will try to load a firmware

Nov 11 13:24:57 thomas-lt kernel: usbcore: registered new interface driver dvb_usb_af9015


if the stick is connected at boot time everything is working correctly.

can someone please give me a hint where to look for the problem?

version is af9015-e0e0e4ee5b33


Best Regards
Thomas

you are not alone with this problem. It only happens 2.6.27 kernels. 
Looks like it does not reconnect device in the USB-bus as it should. I 
don't have access to 2.6.27 kernel yet, so I cannot examine it more. 
Hopefully there is someone who could fix that soon... I think good place 
to test fix is add some sleep (msleep(100)) before/after RECONNECT_USB 
-command around line 685 in af9015.c file. The other solution could be 
to remove whole RECONNECT_USB (after firmware download) and set 
no_reconnect -flag.

Hi Antti,

thank you, that helps.

i have added two lines:

	msleep(1000);
        req.cmd = RECONNECT_USB;
	msleep(1000);

maybe some fine tunnig is required :)
but for me it works fine.

This patch is not OK because it still sends reconnect USB-command. It 
may lead to situation stick reconnects but driver does not except that.

It seems like problem is that it sends USB-reconnect command to the 
stick firmware immediately after firmware is downloaded. Sometimes 
(especially Kernel 2.6.27) USB-reconnect command will be rejected by 
stick firmware because firmware is not started yet. Small sleep just 
before USB-reconnect is needed to ensure stick firmware is running.

Is there anyone who has this problem and can make & test patch?

regards
Antti

Looks better, could you provide signed-off-by?
