Can't use TV Tuner

Hi,

I bought a Mygica ISDB-T tvtuner (s880) and I'm trying to get it to work. When I plug it in this is the message I get in dmesg:

[ 8833.772763] usb 1-1.4: new high-speed USB device number 5 using ehci-pci
[ 8833.859152] Allocating domain for fallback device failed
[ 8833.859155] sms_ir_exit:
[ 8833.859157] smsusb_init_device: line: 409: smscore_register_device(...) failed, rc -12
[ 8833.859827] smsusb: probe of 1-1.4:1.0 failed with error -12

Here is my lsusb:

Bus 001 Device 005: ID 187f:0600 Siano Mobile Silicon

and lsmod:

smsdvb                 17374  0
dvb_core              102038  1 smsdvb
smsusb                 17036  0
smsmdtv                51247  2 smsdvb,smsusb

Re: Can't use TV Tuner

You might try recycling the usb interface.  Remove the ehci modules and remodprobe them.

Thanks for the suggestion, but it didn't work. Same message.

Re: Can't use TV Tuner

You might try to place a debug= parameter on the smsdvb or smsmdtv module in modprobe.d and reload those.  But the complaint comes from the smsusb module.

Re: Can't use TV Tuner

I don't think I know how to do that. I passed debug=1 to modprobe and captured this:

[31350.516712] smsusb_probe: smsusb_probe 0

Re: Can't use TV Tuner

Might've given us a little more information, but error code -12 might give us a clue as to what the problem is claimed to be.
