Hi, just wanted to know where the b2c2-usb driver development is going nowadays? Made an impulse buy of the Technisat AirStar box (rev 2.1 with FlexCop III and TDTC9251DH01C (mt352)) a month ago and would now like to use it in linux, so I'd be very intrested to see it supported. I realize the b2c2-directory under dvb-kernel in cvs is temporary and that the driver is going through lot of changes, still, just for the heck of it I cleaned the 50 or so warnings and errors to get it to compile cleanly against 2.6.11-rc4 (make SUBDIRS=../dvb-kernel/b2c2). (Also requires applying http://www.linuxtv.org/pipermail/linux-dvb/2005-February/000015.html) Attached are the changes made, feel free to ignore it if something else is happening. After modprobing dvb-core mt352 mt312 i2c-core stv0299 nxt2002, and then insmodding b2c2-flexcop.ko and b2c2-flexcop-usb.ko it says .. b2c2-flexcop: B2C2 FlexcopII/II(b)/III digital TV receiver chip loaded successfully b2c2-flexcop: unkown FlexCop Revision: 0. Please report the linux-dvb@xxxxxxxxxxxx b2c2-flexcop: reading of MAC address failed. DVB: registering new adapter (FlexCop Digital TV device). b2c2-flexcop: i2c master_xfer failed b2c2-flexcop: i2c master_xfer failed b2c2-flexcop: i2c master_xfer failed b2c2-flexcop: i2c master_xfer failed i2c_readbytes: i2c read error (addr 0a, err == -121) b2c2-flexcop: i2c master_xfer failed mt312_read: ret == -121 b2c2-flexcop: no frontend driver found for this B2C2/FlexCop adapter usbcore: registered new driver dvb_b2c2_usb So still quite useless, but at least it loads :). Btw, would the specs referred to here http://pvrguide.no-ip.com/bbs-old/viewtopic.php?t=16643 be available from somewhere?
