Aug 6 20:56:34 localhost kernel: [19094.248540] LME2510(C): Firmware
Status: 6 (44)
Aug 6 20:56:34 localhost kernel: [19094.251541] LME2510(C): FRM No
Firmware Found - please install
Aug 6 20:56:34 localhost kernel: [19094.251559] usbcore: registered new
interface driver LME2510C_DVB-S
It is good to print needed fw name. I found it from the documentation,
Documentation/dvb/lmedm04.txt.
Could you drop me that firmware privately as I don't wish to install
Windows drivers in order to extract it.
