I used a Blade 150 workstation, installed the Solaris 9 SPARC operating system, and the problem about the U disk has been plaguing me. My mobile hard disk can be identified and used, but Newman's U disk is always unable to use, the Diamond's U disk of colleagues can be used. I checked countless information, I still failed after I was tried. No way, I have Solaris USB DDK 0.9A under Sun, I am ready to develop a USB driver! The USB of the SPARC workstation is an OHCI interface, while the PC is generally UHCI and EHCI. So I got off the norm of OHCI, UHCI, and EHCI, but the standard is too boring, can't see it! Let's work, wait until it is empty and then study. Solaris is really inconvenient, but I also exercise me, let me learn a lot of underlying things.
