I have the same reader (UltraPlex 40) and MODE SENSE 6 with cd
capabilities page works well under 2.2.14 and 2.2.15
This is the cmd block (OFF is sizeof struct sg_header)
CmdBuff[OFF+0]=MODE_SENSE; //mode sense 6 of course
CmdBuff[OFF+1]=0x08;
CmdBuff[OFF+2]=CD_CAPABILITIES;
CmdBuff[OFF+3]=0;
CmdBuff[OFF+4]=CD_CAPABILITIES_PAGE_LEN+4;
CmdBuff[OFF+5]=0;
You should compare this to the cdb sent to the HA by ioctl at boot. Note
I'm using this via the sg driver
