Fedora Hardware :: USB 3.0 Operating At USB 2.0 Speeds?
Apr 28, 2011
I have enabled the xhci_hcd module, but my usb 3.0 hard disk is still only being recognised at "480MB/s" connection speeds (with benchmarks confirming it is definitely running at usb 2.0 speeds.
The usb 3 controller is the NEC chip everyone seems to be using. The devices is a Seagate free-agent go (something like that anyway) with the usb 3 adapter.
lsusb takes a good couple of minutes to run, and doesn't mention the NEC controller at all, lspci does list it, and devices plugged into it work, but only at usb 2 speeds as mentioned.
I have a relatively high competency with linux (mostly with fedora over the years) so don't worry about solutions or requests that are quite technical.
Happy to provide machine specs if more detail is required, running Fedora 14 x64 with everything up to date. Specs: [URL]
On my machine I currently have 2 internal HD's - sata 3 & running in ahci mode. The bios confirms that they are running at 6G/s. For typical every day use, running apps & such, all seems fine & the machine seems speedy. But when I go to transfer large folders, (20G+) I'm only seeing 70M/s top speed, with 20 to 40 being the norm. (Shoot, I got 20M/s transferring to a usb 2.0 drive.) It doesn't matter if this is from partition to partition on the same drive (A or B) or between drives, or the direction.
So my question is, shouldn't this be giving a LOT faster speeds? Even if the drives ARE at the low end of the speed chart, per say? (WD CAVIAR BLUE 500G & 250G 7200RPM) This also doesn't matter what OS's I'm using either. Also, what ARE the the real world speeds on this? What are YOU ALL getting?
Is there a way by which i can improve my Internet speed. I have a 100Mbps connection but the download speed is only 100kbps. I know that my ISP has limited by connection speed, but i am curious to try as to how i can get the maximum speed.
I have a little bit of a prediciment with my Mobile Broadband dongle, even though I know I'm in a 3G area (Dongle Supports 3G connection) my internet still loads at the normal GPRS speeds max of 5kb/s. Is there anyway to change the speed of it or do I have to keep with GPRS at the moment?
why the operating system is not using swap.I am using Fedora Core 13, it did have 4GB of ram, all of the ram was used. performance was poor. I used free and top to check if it was swapping - according to both, swap was NOT used at all. Never the less, I upgraded to 8GB and performance improved a lot.However, once again, free and top state that ALL the ram is utilised, yet NONE of the swap is utilised.
I presently have Ubuntu and Windows XP Pro installed. By using the GRUB loader I can choose which to load. I would like to install Fedora as a third option, but do not know how this will affect the GRUB and the choices.
I am running F10KDE, and I got fed up with K3b. I am dual-booting with WinVista. I want to upgrade to F11KDE, and keep Vista, too. So, I went to Vista and ran Roxio to make a bootable iso image of the F11 file. Success. Went to boot with the DVD I had just created as a supposed bootable DVD, and got a message: "Missing operating system."
Can I use my all-in-one printer with LINUX Operating System? KODAK All-in-One Printers are designed to to work with WINDOWS XP, WINDOWS VISTA, WINDOWS 7 Operating Systems and with MAC OS. Because of its open-source nature, LINUX OS requires a complex, dedicated support team. LINUX OS represents a very small percentage of installed operating systems in the U.S. As a result, costs for ongoing support and a dedicated support team are not justified at this time.
As Kodak continues to launch products, and as updates are made to LINUX OS, launching LINUX Drivers would require ongoing support and driver updates to Kodak's software. Customer support teams are focusing efforts on current issues concerning the more prevalent WINDOWS and MAC OS; adding support for LINUX OS would take resources away from these issues. Compatibility information for KODAK All-in-One Printers is printed on the retail package so that our customers can be aware of the printer's hardware and software requirements at the time or purchase. For more information about specifications and compatibility, visit KODAK All-in-One Printers.
How do I get a DVD-R and its contents to be recognized by the operating system? I know there is a "mount" command somewhere, and to unmount there is the "umount". I just don't know how to use these.
I installed Fedora 14 in a dual boot with Windows 7 (Win 7 came preinstalled on my Vaio, I freed up 30 GB on a hard disk drive and installed Fedora in it).The first reboot took me straight to Windows. I could not find a way to get multiple Operating systems, so I tried looking on the net a bit, and installed EasyBCD. This gave me the option of choosing the boot up OS. But when I choose Fedora in the options, the screen changes to GRUB4DOS which lists Fedora and Other as my two boot options.Selecting either one of these options results in Error 22 No partition found.
Can one make a self booting installation ISO on a flash drive of Fedora 14 as it is, with all my files being in the new install, so I can install this modified operating system on my relatives computers just like I have it on mine, or for if ever the operating system on mine fails, so I can use this flash drive ISO to reinstall the operating system on mine just like I like it, just like it is now? If this can be done, please tell me how you do it, or kindly provide me with a link to a page that has this information.
Just recently installed fedora 11 64-bit on my laptop. Everything was fine until today. Everytime I boot up, it crashes right after the desktop loads. Everything is loaded except the area where the running programs are on the taskbar is just one big white block. And a bubble popup says "New SELinux security alert. AVC denial." but everything is frozen. Can't move the cursor or use keyboard. and nothing is happening on the screen. Completly frozen. Anybody have any ideas on what is wrong and how to fix it?
I am currently using ubuntu 9.04 and I am planning to have a dual boot my system with fedora 12. My computer is quite old and I have RAM of 256 MB DIMM 266 MHZ with pentium 4 processor. So will the dual operating systems work in my computer??
I have a fancy new Quad Core Xeon machine here that I'm trying to install F10 x64 on. The installation went fine. When it reboots the first time, though, I get the dreaded Error Loading OS.
So I dug up my bookmark of the awesome Grub HOWTO here and followed the steps to install Grub manually. Alas, I get the same result after installing it. Even tried doing a makeactive (hd0) just in case, but no luck.
I did more searching and searched for "raid install" but didn't find anything helpful. So here I am... hoping somebody has some insight.

I have installed Fedora 10 on a Dell M6400. It has 2 disks in a mirror raid. It came with Windows Vista, but I am not doing a dual boot setup. I have formattet the disk with this installation.I downloaded http://ftp.crc.dk/fedora/linux/relea...0-i386-DVD.iso, burned the DVD and did the install check. It passed the check.The installation went fine, but after the first reboot I am getting "Missing operating system".
I have no idea where to begin... Could the installation media be faulty after all? I there anyway to get passed this, without reinstalling? I know this may have something to do with the boot loader, but I don't know anything about it.I have installed Fedora 4,5,6,8,9 and this never happened to me before, but then again, I did all these installations on my old Dell Latitude.... Could this have something to do with the new hardware?
I am unable to Install Fedora10 in my system as one of the multiple operating systems and it gets hanged after probing for Hardware devices and so ...I get fedora trademark sought of symbol and even after waiting any amount of time it doesnt go further..neither the keyboard works nor the mouse pointer moves... I am stuck at this screen shown in the installation screenshot...I get this screen however I dont get the options back or next or its that I am unable to see this options on the screen at all and mouse gets hanged and even keyboard doesnt work...
[code]....
Initially after booting with the media it doesnt even prompt me to press any key to boot from CD or Dvd or I get any screen to select the option for the mode of installation like text based installation or graphical installation..it hardly shows me this screen for even a fraction of second as well...
It takes me to the screen
1) Install or upgrade fedora 2) rescue existing installation... 3) 4) Memory test
when I click on install fedora I am taken to the fedora splash screen and nothing goes ahead... I tried in rescue mode as well... In rescue mode it asks me for language selection...keyboard layout... later it doesnt go ahead as well... I have checked the installation media and it confirmed that the installation media is good... I use Redhat 4.1 version and It works fine except for the message drivers/usb/hid.c core message received at :75 while trying to restart shutdown or access a virtual console... Along with Redhat and while trying to install fedora I have windows server 2008,Windows vista on that harddisk...
I'm dual booting Mac and Fedora 11. My music is on the mac side, and is too large to copy to the Fedora partition. What is the best option for sharing between the two partitions. I used to copy the itunes folder to public, but that allows anyone access.
What's the best way to do this without allowing complete access?
I am a newby in linux. i wanted to install lampp (xampp) but it gaves me an error that the operating system doesn't support 32 bit. I am using at this moment Fedora 12 x86_64.
I looked in another thread and they sad that i need to run yum whatprovides missing_lib_name but it don't show anything is there another way to get 32 bit support in linux because i really need xampp.
problem is that no lower speeds available and ondemand do not work it always stays at 2 GHz even when maxing out all 4 cpu-s with something like Blender render for example?
I can't get Gkrellm to show my fan speeds anymore since reinstalling Ubuntu.I have tried 9.10 and 10.04 and tried installing packages to maybe get the drop down to show up for fan speed but still nothing.I have installed Xsensors and that shows fan speeds correctly but I want to show them in Gkrellm like I used to have. Now every other temp gauge is working like it used to but the fan speed monitor.
I am using Ubuntu 10.04 and my internet works fine except for my download speeds. In Windows, downloading the same file, it downloads at around 200kb/s but in Ubuntu, it hovers around 20kb/s and never tops 50kb/s. Any idea how I can fix this because I really don't want to go back to Windows but I may have to.
I am new to Linux and have recently dropped Windows 7 (and windows all together for that matter) for Ubuntu 10.04.I love the look and feel of Linux and enjoy using it more over Windows. Despite this I am experiencing a serious problem which may cause me to revert back to Windows 7.I have a USB 3G modem: ZTE MF622 on the KKTCELL network.I have got this modem to work with wvdial and Gnome PPP, however i cannot get speeds over 60kb, Windows gives me well over 200kb.
I have tried a number of things but nothing has worked, it seems that no-one has posted a solution to this annoying conundrum.
I'm currently downloading some files using wget. According to wget, the download speed is 40-45K/s. But according to the System Monitor, I'm downloading at a rate of 80-100KiB/s. What can explain this contradiction in download speeds? I'm not downloading updates or anything like that: wget, so far as I can tell, is the only downloading.
I am running 2 gtx 480 gpu's. I got the fan to overclock on one of them by using "Option" "Coolbits" "5". But adding that to the second device section in xorg.conf doesn't produce any results in nvidia-settings. Would anyone be willing to post their xorg.conf if they have got this working?
