After some time spent with "Usbsnoop.log" , I extract firmware from windows
driver for DVBWorld DVB-S 2102 USB2.0 ("DVBUSBS2102.sys"). It appears 8192
bytes long with many AA's at end - like Pvrusb2 firmware for Cypress CPU.
I replaced "opera1.fw" with extracted by me firmware and changed USB ID
in "opera1.c". Now I get error:
dvb-usb: firmware download failed at 8134 with -22
Why was that?
