kernel 3.0 and very slow usb

frlinux · 2011-08-15 20:04:10

Hello,

I have a problem with ALL USB devices on my Arch Linux installation, it used to be very fast then after Linux 3.0, all USB transfer are very very slow. I tested a few usb sticks/drives and regardless of filesystem, I get the same issue. I have timed a transfer, to transfer 160MB, it took 2m39s, it is way too slow. It used to be able to do about 30MB/s sustained.

Anyone got the same behavior?

Perhaps you can post the usb mode....2.0 ...or 3.0. That should provide some guidance for troubleshooting.

Sorry, USB 2.0

As you can see, it says not running at top speed, this is connected to the front of the machine, where I always connected my drives. Windows gets full speed, only Linux is affected.

Connecting to the back of the machine works, but my point is that it used to work at the front as well, and full speed. Here is an output of the device connected on the back;

The info you provided is indeed most helpful since it defines the specific problem introduce by Linux 3.0 kernel.

The possibility exists in the kernel config arrangement such that modprobe might be of use to you.

If you have the previous kernel26 kernel config you might find a difference with the Linux 3.0 in the usb arena.

lilsirecho · 2011-08-15 21:21:01

Perhaps ls usb and/or lsmod will give some clues.
