Can The 3100 Host Usb Devs At 2.0 Speeds?

[neuroshock]

Hello,

Can someone verify if the SL-C3100 can host USB devices at USB 2.0 speeds? Specifically, is the USB Host truly 2.0 or is it lamed to USB 1.1 like the SL-6000 series?  

Further, if the C3100 CAN sustain data transfers that high is the system bus processing speed high enough to be able to utilize it?

I'm considering selling a brand new 6000 I just purchased to buy a C3100 with the proceeds, but this particular piece of information will be a key factor in my decision.

Thanks All,

It does USB 2.0 Full Speed - 12Mbps, see my website for details.

12 Mbps is usb 1.  Is there some additional protocal stuff that might make a 12Mbps connection "usb 2?"
The spec for usb 2 (as you surely know) is 480 mbps.

Bzzzt. Try again.

Due to the USB standards commission basically losing their minds, they renamed the USB 2 modes.

USB 2 "High Speed" is 480 Mbps
USB 2 "Full Speed" is 12 Mbps.
USB 2 "Low Speed" is 1.5 Mbps.

Basically *everything* can legally be called USB 2.

The reason why the Zaurus really is USB 2 is because the USB port on it is technically a USB 2.0 OTG (On The Go) port. That is the specification that defines the Mini-A Host/Mini-B Client dual use port. It still runs at 12 Mbps "Full-Speed" though.

....and so all usb is usb 2 (except possibly previously and so non-retractably designated usb 1  devices which pre-existed the paradigm-shift of "twoness" in usbness, right? LMAO), making the designation meaningless?    
Doesn't this render the initial question meaningless as well?

Gotta love marketing. Who cares about technical accuracy or details as long as marketing get their way and it improves sales

[neuroshock]

My thoughts exactly.  The bottom line is that data throughput is no better than that on my 6k that I've owned for a year. *sigh* I'm sorry to hear that.

     Don't get me wrong, it's still awesome that they finally made some clam-shells with USB host, but it looks like I'll be staying with my 6000's for the moment.  Since my SL-6000L has a larger and more beautiful screen, (I've seen both now and there IS an instantly identifiable difference in quality, especially in high-light areas such as outdoors), built-in WiFi, and two available CF slots that I can fill with any device(s) I wish, - (rather than having one mandatorially occupied by a Micro-Drive), and longer battery life - (I have/use the CF Expansion sled) I just cannot forsee switching to the more fragile clamshell design that is point for point identical or inferior to what I already have in every respect.  Having said that, I must admit until lately when we finally had some alternate ROM choices I would have swung in favor of the cXXXX line but that disparity has been balanced thanks to pdaXrom, Cacko, and Guyhelm. A BIG THANK YOU to all of those teams btw!

     Which is lame of SHARP in my opinion because SHARP USA released the 6000's over a YEAR ago and they discontinued the line, meanwhile SHARP JAPAN has been cranking out new devices during that time and STILL doesn't have a superior device to offer.  That MUST have been the stupidest marketing decision in the history of mankind.

Ah well, I think I'll sell that extra 6000 anyway just so I'll have the Christmas money. It's possible I may become bored enough to buy a C3100one if I can afford it just to have something new to play around with, C3100 and clamshell owners feel free to twist my arm by pointing out good reasons I've overlooked to do this.  I'm like Mulder- I want to believe.

the problem with speed is not a SHARP one, its an intel one, they havent produced any chips in the pxa range that are usb2.0 High speed. you need to add an external chip for that and unfortunattly most of those are USB 2.0 to PCI which the pxa cant do without another chip that does, Xscale to pci, which are exspencive

mabey the next gen of chips that intel anounced will address this

Intel would have to have a huge gaping hole in their head to not put 480Mbps USB 2 in their next chip.

Funnily enough, it would match the gaping hole in Sharp, USA's marketing dept.

And as for the 6000 vs Clamshells, it is the clamshell form factor and built in HD that sway me away from using the 6000. The keyboard on the 6k, with no built in number row, drives me nuts. Additionally, the lack of multimedia remote and the tiny headphone jack make it practically useless as an MP3 player for me as well. Coupled with the poor (relative to the newer iwmmx accelerated clamshells) video performance, there isn't any way I could use my 6k day to day.

Instead, I'm using the 6k to build a robot  (Hey, it's the only Z that can use Wifi, the  Sharp CF camera, and the serial cable simultaneously.)

Well, Archos did that - their PMA400 supports USB 2.0 High Speed when conecting to a PC.

I realize this topic is starting to waggle all over the place but believe it or not it's still helping me, so have mercy on it please!

That's just the kind of specified opinion I'm looking for that may sway me to try the dark side of the force...er uh...a clamshell.  Thanks a LOT...serious things to think about.

The lack of a number row doesn't really bother me.  I've never used the multimedia remote- I now wonder what I'm missing.  The headphone jack is also a piece of cake to fix so that's not really an issue either.

Now that you mention it however the video performance really IS beginning to be an issue with me.  But let me ask this:

Does the SL-C3100 have one of these "newer iwmmx accelerated" chipset/driver/whateveritis?  Or does it have a distinctly different video chipset/driver different from everything else like the sl-6000 does?

Er maybe it would be better to ask this:

Do any/all of the current Rom's make the video performance similar to, (or better than), the C860 for example?  Or if I dive in and buy a C3100 will I have to wait and wait and wait forever to get Video Acceleration on it as well?

Sometimes it's "Better to go with the devil you know..."

Keep the opinions and pointers coming!  I'll make a new thread if need be.  I really want to see what drives ppl to these clamshells, and need to decide if I wanna be an owner of one or not.  (I WILL be keeping one of my 6k's just because I can't bear not being able to surf the net with that beauuuuuutiful screen when I'm laid up-I'm disabled and spend way too much time in the hospital etc.)

Preach to me ppl, let me hear your cries for reason! I WANT TO BELIEVE... and while I see a bit to think about,  it's certainly not a "slam dunk".

Well, the remote makes it act just like an mp3 player. You never even have to open the machine - you press the play button, the Z starts, loads the media player, and starts playing. I've owned the remote for both the 860 and the 3000, and I wouldn't be without it. It was the first accessory I insisted on tracking down for the 3k.

As for the headphone jack, the other issue is that it sticks out the side. I put my 3k in my jacket pocket, and having the jack sticking out the side a) won't fit, and  is just asking to get caught and damaged on something. The 6k was designed like a phone instead of an mp3 player

Cacko 1.23 has been released for the 1000/3100, and the video playback performance is astonishing. This is the first time I've been able to play unmodified divx videos. Specially encoded ones do perform better, and I can get 640x480 full screen, stereo sound videos playing easily.

I wanted to like the 6k, I really did. The screen is beautiful, and built in wi-fi is very nice, but the 64mb of built in storage, keyboard, and inability to use it for music pretty much killed it for me.

I really like the clamshells, and the video playback under cacko 1.23 is so good that I went out and grabbed a 6gb microdrive to start toting movies with me.

Now THAT was the straw that broke the camel's back.  I'm getting me a 3100 and the first sl-6000l will hit ebay within the next 24 hours.  If I find I can live with the screen I may sell another one as well.

I'm beginning to see why Adf and the others are wishing we could pop the 6000's screen into a C3100.  That would make it perfect. But for the mean-time there's no doubt. I'll be a SL-3100 owner soon.

Thanks for helping me form a better informed decision.

the c*K series all have iwmmxt capable processors, thats why you can do moives without reencoding, only problem is i have found it kills the battery life depending on the encoding options and quality of the stream. recomend external battery for moive playing.
