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.
