have tried hasn't worked ? sure class want want ? trying achieve think need modify bytes in boot sector of usb flash drive ?

modify device @ such level under unix, require access character device special file present device in "raw" mode. under os x, believe these files /dev/rdisk# # replaced disk number.

nsworkspace doesn't sound need @ all, except maybe list of mounted media using - (nsarray *)mountedremovablemedia method. frankly, won't give dsf usb media. openfile doesn't think does, acts if you've double clicked file.

need bit deeper here, i/o kit api more in-tune want do, along i/o registry :

once have info usb device, go standard ansi c or posix stuff manipulate bits in file (fopen()/open(), fseek(), fprintf()/fputc(), fclose()/close()).
