[linux-dvb] what does err code -22 means in function usb_cypress_load_firmware???

[CIJOML]

Hello,

I am trying Opera driver, but having problem with firmware load.
1st part of firmware opera1.fw 
http://www.informatik.uni-leipzig.de/bsv/Hlawit/dvb/opera1.fw
doesn't load.

Does anybody can help me to fix this? I am not familiar with this part of 
linux-dvb code

Error message is:

dvb-usb: found a 'Opera1 DVB-S USB2.0' in cold state, will try to load a 
firmware
dvb-usb: downloading firmware from file 'opera1.fw'
dvb-usb: firmware download failed at 9418 with -22

Thanks a lot

Michal
