Firmware Update Over SCSI

[Anu P]

Hello,

I am planning to develop firmware updater tool for my USB device. My USB device accepts SCSI commands.

When I read couple of blogs, I got a feeling that I have to develop a "kext" module which can issue SCSI commands.

If that is the case, I need to go through kext signing formalities, kext installation needs administrator privileges etc. 

Could someone please confirm that issuing SCSI command over "kext" module is the correct approach to update USB firmware? If not so, please recommend the right approach.

Thanks,

Anurag

I can confirm that it is necessary to develop a kernel extension (kext) in order to control SCSI device. Or rather it was the case 3.5 years ago when I had to do this. It may change since but I doubt it.

Boris.

Hi Anurag —

What SCSI peripheral device type is your device?

The answer to your question depends on whether it is a device that requires an in-kernel logical unit driver or not.

Thanks,

Hi Chris and Boris,

Thanks for the response!

My device is USB mass storage.
