[linux-dvb] random "no frontend was attached"

[Tomasz Chmielewski]

I have a DVB USB device which identifies as:

# lsusb
Bus 001 Device 006: ID 04ca:f001 Lite-On Technology Corp.


Randomly, upon machine bootup, it is not detected properly ("no frontend was attached"):

usb 1-6: new high speed USB device using ehci_hcd and address 4                                                              
usb 1-6: configuration #1 chosen from 1 choice                                                                               
dvb-usb: found a 'LITE-ON USB2.0 DVB-T Tuner' in warm state.                                                                 
dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.                                              
DVB: registering new adapter (LITE-ON USB2.0 DVB-T Tuner)                                                                    
dvb-usb: no frontend was attached by 'LITE-ON USB2.0 DVB-T Tuner'                                                            
input: IR-receiver inside an USB DVB receiver as /class/input/input6                                                         
dvb-usb: schedule remote query interval to 150 msecs.                                                                        
dvb-usb: LITE-ON USB2.0 DVB-T Tuner successfully initialized and connected.


As a result, using DVB is impossible until I plug the device out 
and plug it in again.

This is the only solution to bring it back to life - if I remove
DVB modules and insert them again, I get:

dvb-usb: bulk message failed: -22 (1/2)                                                                                      
dvb-usb: bulk message failed: -22 (1/-150651080)                                                                             
dvb-usb: bulk message failed: -22 (1/662)                                                                                    
dvb-usb: bulk message failed: -22 (1/1024)                                                                                   
dvb-usb: bulk message failed: -22 (1/2)          


Are there any "better" solutions to that, other then re-inserting the USB device?
If not, what could be the cause of it?

I use Linux kernel 2.6.28.

Does not work here.

It does not work always for me as well. Sometimes, I have to replug the 
device 2-3-4 times until it's eventually properly detected.
Most of the time, it's not detected initially.

Did it work for you properly with earlier kernels?

I noticed that after I do (without device unplugging/replugging):

# rmmod dvb_usb_dibusb_mc dvb_usb_dibusb_common dib3000mc dibx000_common ehci_hcd

# modprobe -a dvb_usb_dibusb_mc dvb_usb_dibusb_common dib3000mc dibx000_common ehci_hcd


it is detected properly _always_.

With what earlier kernels does it for you?

thanks for pointing the right direction.
try this if it works for cold and warm boot (machine/device), too:

tom1:~# grep hcd /etc/modprobe.d/dvb
install ehci-hcd /sbin/modprobe dvb_usb_dibusb_mc; /sbin/modprobe --ignore-install ehci-hcd

no.
needed this to get it work after linux cold boot:

tom1:~# cat /etc/modprobe.d/usb
install uhci-hcd /sbin/modprobe ehci-hcd; /sbin/modprobe --ignore-install uhci-hcd

tom1:~# cat /etc/modprobe.d/dvb
...
install dvb_usb_dibusb_mc /sbin/modprobe --ignore-install dvb_usb_dibusb_mc; \
/sbin/modprobe -r dvb_usb_dibusb_mc ehci_hcd; \
/sbin/modprobe -a --ignore-install dvb_usb_dibusb_mc ehci_hcd
# runvdr

but second is ignored by udev and/or modprobe at bootup for some reason, 

tom1:~# dmesg |grep frontend
DVB: registering adapter 0 frontend 0 (Philips TDA10021 DVB-C)...
DVB: registering adapter 1 frontend 0 (VLSI VES1820 DVB-C)...
dvb-usb: no frontend was attached by 'LITE-ON USB2.0 DVB-T Tuner'
dvb-usb: no frontend was attached by 'LITE-ON USB2.0 DVB-T Tuner'
DVB: registering adapter 2 frontend 0 (DiBcom 3000MC/P)...

so I need

Can You pls confirm this, I won't touch the driver code before, maybe usb-h/w dependant.

I noticed it is probably enough to remove ehci_hcd.
In that case, the device will be re-detected on uhci_hcd (which is USB 1.1).
And if you remove uhci_hcd and insert ehci_hcd again, it will be 
re-detected there.
