 |
|
Hi,
I'm trying to use an usb2 external harddrive but I just realise that USB2 doesen't work on my notebook, only USB1.
As a result, transfer rates are too slow to make the harddrive really usable:
'hdparm -t /dev/sdb'
| Code: |
/dev/sdb:
Timing buffered disk reads: 4 MB in 4.32 seconds = 947.60 kB/sec
|
Here is what lspci shows:
| Code: |
00:00.0 Host bridge: Intel Corporation Mobile 915GM/PM/GMS/910GML Express Processor to DRAM Controller (rev 04)
00:01.0 PCI bridge: Intel Corporation Mobile 915GM/PM Express PCI Express Root Port (rev 04)

01:0c.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8169 Gigabit Ethernet (rev 10)
03:00.0 VGA compatible controller: nVidia Corporation NV43 [GeForce Go 6600] (rev a2)
|
As you can see, the EHCI controller is not even recognised. there should be a line like this one :
| Code: |
00:1d.7 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB2 EHCI Controller (rev 04)
|
Does anyone has an idea as to why it doesn't work ? |

| If a PCI device doesn't appear at all in lspci, it usually means the BIOS disabled it. So check in the BIOS if you don't have an option to select between "EHCI" and "UHCI" or between "USB 2.0" and "USB 1.1". |

Thanks widan.
I checked my BIOS but there was no "visible" option related to USB.
However, I got the solution from someone on the Uniwill forum.
Apprently it is an "hidden" option that got somehow disabled. 
I did a "Load optimized default" and - while in appearence there was no change on the BIOS screens - EHCI was detected at the next boot. |
