I need some one help me to add some feature for an opensource CLI software.

I want to send customized CDB (SCSI commands) to my USB mass storage device. And read back. Currently I am using the sg_raw from sg3_utils-1.46mgw32 to send. Like [login to view URL] [ sg_raw -r 512 pd1 25 00 00 00 00 00 00 00 00 00 -n sg_raw -s 512 -i [login to view URL] pd1 2a 00 00 00 01 00 00 00 01 00 -n sg_raw -r 512 pd1 28 00 00 00 01 00 00 00 01 00 -n ] below is what I need: 1. I have a lot of data to input. Let's say, more than 100k lines. The speed of sending 100k lines commands from windows cli with sg_raw is too slow. I need to improve this. So you need to fimplify the operation from 100k lines to 1 line. like sg_raw_customized [login to view URL] so the tool will send all the data one by one. 2. I need you to create a tool to generate the [login to view URL] in above. I will let you know how to do that. Basically you just need to convert some strings(CDB content) to the all.dat. 3. I also need you add the feature for sg_raw to read data and output to screen (windows cli) and save to bin file or text file. 4. the test file or bin file generated from item 3 in above will be able to used by sg_raw to write data into the device. The sg_raw is the option I am using. If you have better solution, like using python framework, that will be acceptable. You can let me know. But the most important thing is the performance. If the performance is good, I am ok.
