Myrkat's Theory of USB 2.0 on the 8887
|Originally posted by beebster83
Well, the device manager lists 3 Universal Host Controllers by Intel, 6 Root Hubs, 2 revision 5 or later Companion Controllers by via, and 1 enhanced host controller by via... I can't tell how any of that divides well with 4 USB ports except that maybe the mp3 player docking bay is actually a USB part... Any ideas?
First of all, this really answers the previous 3 questions - or at leasts attempts to:[list=1][*]I believe the SD/mp3 player are USB 1.1 - I'm VERY certain of it, infact.
[*]I believe the MemoryStick reader is also USB 1.1 - I have no MemSticks to prove it, but I feel confident it's NOT usb2.0
[*]The four USB 2.0 ports may have their own controller, seperate from the SD & MS readers. I highly doubt they have two controllers (2 on each), so any USB1.1 device plugged in will lower the performance of a USB2.0 device plugged in.
[*]I noticed a performance gain with one of my external usb2.0 HD's (it's also firewire) when I had nothing plugged in. Granted, it was nowhere near as efficient as using the firewire port (for the same drive), but it was better than when I used the USB2.0 while my mouse was plugged in.
[*]I would not try usb2.0 to burn DVD's - I'm sure it's just fine. I just don't trust USB for critical work.[/list=1]
And as for whether external Sony owners burn + or -, well, I've equally done both (did a bunch of +R burns for copying from DVD-R to DVD+R) and I've also done many DVD-R's as well.
I bought (2) 50-piece spindles, one of each (2x media, though). And I have not played with the ±RW stuff (I never did CDRW, either...)
