Hi all,
I want to write a program in C that can enumerate all USB massand their mount point storage on my system. i want to give ability to copy one file to desired USB mass storage or read a file from it. I have posted another question about how can recieve USB arrival in this forum.
I think that this will possible with navigating into /proc/partitions and /proc/mounts is there any other way?

NAME

       usba, usb - Solaris USB Architecture (USBA)

       USB provides a low-cost means for attaching peripheral devices, including mass-storage devices, keyboards, mice, and printers, to a system.
       For complete information on USB, go to the USB website at http://www.usb.org.

       USBA supports 126 hot-pluggable USB devices per USB bus. The maximum data transfer rate is 1.5 Mbits (low speed USB 1.x) or 12 Mbits  (full
       speed USB 1.x) or 480 MBits (high speed USB 2.0) Mbits per second (Mbps).

       USBA adheres to the Universal Serial Bus 2.0 specification and provides a transport layer abstraction to USB client drivers.

FILES

       Listed below are drivers and modules which either utilize or are utilized by USBA. Drivers in /kernel/drv are 32 bit drivers ( only). Driv-
       ers in /kernel/drv/sparcv9 or /kernel/drv/amd64 are 64 bit drivers.
