Unable to send SCSI commands to USB Drive
I am connecting a USB mass storage removeable drive to Solaris 10 x86 machine.

The device is detected and i am able to perform standard read and write functions.
But i want to use a code to send IOCTL based SCSI commands to the same device to read and write the data. Which i am unable to do so. I have learned from internet that this is not possible due to MPXI/O can anyone tell me a way out.

USB is not SCSI.

Take note of Corona688's reply and do some research...

Small Computer System(s) Interface - a parallel interface.

Universal Serial Bus - a serial interface, usually P-n-P but may require specific drivers.

Actually USB does have a well-specified SCSI command set. Look up the UAS (USB Attached SCSI - T10/2095-D) and the UASP (Universal Serial Bus Mass Storage Class - USB Attached SCSI Protocol) specifications.

I do not know if Solaris has IOCTLs or a library that support either specification.

I use SCSI.dll on Windows OS based PC and SCSI.h and SG.h on Linux OS based PC to do SCSI command set communication with USB Mass Storage devices. Typically READ10 and WRITE10 SCSI commands are excuted with ease using IOCTL on both OS's. I want to do the same on Solaris x86 please guide me

Does it show up as a disk or not? What does "rmformat" show?
