Hi, * .* |

I have a small problem with usb in my laptop. First I had all 3 HCD |
| 4 |
compiled in my kernel: ehci, ohci and uhci. When I connected some usb |
| 5 |
2.0 device (hard drive or external DVD burner), there was a message in |
| 6 |
/var/log/everything/current that device is not running at full speed and |
| 7 |
that I should connect it to a faster hub and it was using ohci. I tried |
| 8 |
all four ports I have and it was the same. I tested the device (that is |
| 9 |
a hard-drive) with "hdparm -tT /dev/sda" and it gave about 900 kbyte/s, |
| 10 |
which is something like usb 1.x. |
| 11 |
|
| 12 |
Then I recompiled my kernel with ehci only. Now there is no such |
| 13 |
message, the same device is using ehci and when I test it, it gives more |
| 14 |
than 20 Mbytes/s, which must be USB 2.0, as I want. |
| 15 |
|
| 16 |
The problem is: why when I have compiled ohci also, the device does not |
| 17 |
work as USB 2.0? I could work with ehci only, but the problem is that |
| 18 |
now my usb mouse is not working (it is not usb 2.0). |
| 19 |
|
| 20 |
I read the help to all selections in kernel config under USB support. |
| 21 |
There is no thing like "select fastest driver"... They say that it is no |
| 22 |
harm to select all HCDs... |

This is the relevant part of the output from "lspci -v": |

I also came to idea that maybe the first device I connect is determining the speed for all ports (the first is also USB1.x mouse). So I disconnected the mouse and plugged the USB2 devices first, but no difference. |

Yesterday I updated my kernel to 2.6.12-gentoo-r10, but it is the same. |
| 51 |
|
| 52 |
Any clues? |
| 53 |
Any proper kernel configs for this part? |
| 54 |
|
| 55 |
Thanks in advance. |
