Hi Antti
Yes, there missing error handling when no firmware file found.
It seems that this is more of a problem with udev-182+.
However, so far udev-182 is only a problem on first ever plug.

Do we need fw blob anymore!?

is no longer used."

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.

Hi Antti,
Yes, this is a good idea to print the firmware it finds and then
selects.

It would be interesting to see if your firmware is newer, my two boxes
are over a year old.
I as sure the firmware has a bug.
