Whats with the USB 3.0 speed?

[Chilly Willy]

Shouldn't I be able to get the same speed in F16 as I do on W7?


On W7 I get a sustained speed of around 40M (+/-). On F16 I get about 20.

The 'usb-devices' command might give a hint what's wrong, if you run it, you'll see something like:

(bolded by me to point out the values to look at)
for a usb 2.0 (high speed) and usb 1.1 (full speed) device, try to confirm you see a Ver= 3.0 and Spd=5000 for your usb 3.0 device. It could be the xhci_hcd support just isn't starting for some reason and it's lapsing back to 2.0 (note that "uhci" is usb 1.1, "ehci" is 2.0 and "xhci" for 3.0). This way you can look for the "Product" line that shows your XHCI controller was found and seems to be working and the 3.0 using device

Here is what I get: (with the drive plugged in, of course) - I included it all because as you can see where I mark is questionable. After that, seems OK...

So, what do you think? - It seems to me that since the drive is using bus 9, it SHOULD work.

Hello
wasn't there a problem with usb 3 on the latest kernel, I say latest, probably months ago now.
Do a search on the forum I'm sure there was a command/patch for those with usb 3.

[Chilly Willy]

The only thing *I* know of was in F14, it was disabled as it screwed up suspend (big deal!) why I upgraded & STILL having issues. There WAS a way to get it working for it but the directions were go vague for me to get it going.

I'll look around the forum as soon as I can...

---------- Post added at 02:18 PM ---------- Previous post was at 12:25 PM ----------

Didn't really find much (if anything at all) that related to F16 (even through google), let alone speed. It all seemed to relate to F14 not working.

[Chilly Willy]

IF there is a way to resolve this, I'd like to ASAP. I have a bunch of files to transfer & catalog & quite frankly, slow doesn't cut it at all & using W7 is a PITA (even though it works), the way they have you do it!

[marko]

All I can think of trying now it to try booting to one of the earlier kernels in the grub list when you boot up. I assume you're booting to the newest one which is 3.1.6 (I think I have fedora 15 here at the moment). Probably pretty soon a new kernel will come out and resolve it

[Chilly Willy]

OK - I hope so...

(no lesser kernel - but if a new one is due soon, I probably can wait a LITTLE while)

[Chilly Willy]

No I just recently preupgraded from F14 to F16 so I only have the 3.1.6 one listed. (twice, once as normal & another as recovery mode)

[Chilly Willy]

I just got the new kernel & I'm sad to report that it did NOT help. So NOW what? (maybe a future kernel like 3.2 ?)

If it wasn't for the fact that it DOES work under M$ (all be it still slower than I'd like - but still 2X faster than F16) I'd be looking at a HW (port ?) issue for sure. MoBo does have a sound issue that it needs RMA'd on, maybe that will fix this too, but I'd rather doubt it.

[Chilly Willy]

I just noticed one thing that is different in my two OS's that I wonder about it's affect on this USB issue. My F16 is throttling back it's CPU clock speed, where it appears that W7 is running at full speed. Would the fact that F16 has my CPU cores running a 800Mhz [idle] (out of it's 3.2Ghz) have any affect? - it seems to me that if it did, the system would kick up the speed when needed.

[smr54]

Rupert mentioned something similar. Go to http://forums.fedoraforum.org/showth...=211792&page=8

Around post 119 they start discussing it, with, I believe, some workarounds

[Chilly Willy]

Thanks for the info but I didn't see any mention of how this affects the USB 3.0 speeds & THAT is what I wanted to know about.

I know that the CPU clock speed affects the whole system speed & that it running faster will make everything faster, but if it IS a case of clock speed, then shouldn't the system kick up, or is this part of this throttling "bug"? (just an observation that got me wondering...)

The throttling isn't so much of an issue with me, IF it works like it should & kicks up when needed, otherwise I TOO may have to resort in shutting it off & running full speed. (especially if it is causing my issue)

Is the slow performance on an ntfs filesystem?
