RE: HP Prime wireless kit
Quote:Not to be picky, but the advantage isn't the absence of drivers, but rather that every device is certain to have one, right?Right. HID devices use the OS's generic HID driver, instead of requiring a specific driver. Quote:That also sorta explains the 'MOUSE' function on the Prime: probably refers to the USB interface, not that a mouse might be attached to a calculator! (or could be the touch screen, IDK)MOUSE is indeed for the touch screen, not for using the Prime as a HID mouse. The TI-89T can behave as both an USB HID mouse and HID keyboard through a third-party program, but not the Prime, AFAWCT. Quote:BTW, I have reason to believe that Windows programs run better wrapped in the Mac OS, particularly where I/O is involved.Agreed for disk I/O, as Windows' disk scheduler is notoriously bad: the usual Windows disk benchmarks running through Wine under Linux (not even virtualization) traditionally yield much better results than on native Windows. That's less of a given for network or USB I/O, for which virtualization often reduces (or at least, does not improve) throughput and/or reliability. Quote:IMHO, the USB is plenty quick for the Prime, YMMV.That's because you only have few, small files USB on the Prime is annoyingly slow with several hundreds of KBs, let alone dozens of MBs. The protocol on top of HID is missing the "directory list" commands supported by most of the TI-Z80, TI-68k and TI-Nspire series: the dirlist command triggers a mere enumeration of the calculator's contents, instead of a lengthy, all-or-nothing backup. |
