 |
|
Hi there,
I installed Gentoo on my notebook and everything is working fine except usb 2.0.
I've an external usb 2.0 harddrive attached but it only works with usb 1.1
I think the reason is that the usb 2.0 module (ehci-hcd) doesn't seem to work with my hardware.
I tried the gentoo sources 2.4.20-r5 and am now trying the vanilla sources 2.4.22-pre8 because i hoped they could help me.
lspci says:

so it seems like I have an Intel 82801BA/BAM usb-controller
Actually I am not sure if this chip is able to do usb 2.0 but I hope so. At least it was advertised like this when I bought my notebook. (If not my dealer will have a very unsatisfied customer)
when i try to load the ehci-hcd module it says: | Code: |
/lib/modules/2.4.22-pre8/kernel/drivers/usb/host/ehci-hcd.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
/lib/modules/2.4.22-pre8/kernel/drivers/usb/host/ehci-hcd.o: insmod /lib/modules/2.4.22-pre8/kernel/drivers/usb/host/ehci-hcd.o failed
/lib/modules/2.4.22-pre8/kernel/drivers/usb/host/ehci-hcd.o: insmod ehci-hcd failed
|
usb 1.1 works fine using the usb-uhci module and i can access the usb harddrive without problems ... and without speed 
I hope you guys can help me!
Cheers
Michael

hi there,
i got the same problem as you, the only difference is that i have a SiS usb2-chipset.
afaik only the nec-chipset is supported by 2.4.2X
so hopyfully the 2.6 bring us a good and working support for the most usb2-chipsets =)

Hi barbar.
It seems like we have different chipsets. Reading through the intel-datasheet it looks like you have the ICH4 chipset which supports usb 2.0.
I am pretty sure I've got the ICH2 chipset which would not support usb 2.0 even if the box of my notebook and the advertisment of my dealer say it does. (I am getting pretty angry with Gericom and Saturn in Germany ... just to mention this)
But, nevertheless, I read a bit in this document: http://www.linux-usb.org/usb2.html
It says: | Quote: | | ... Works with a variety of EHCI silicon implementations. NEC led the market by over a year, but now implementations from Intel (ICH4), NVidia (NForce2), Philips and VIA (vt62x2, vt8235) also work with that driver. Other implementations (ALI, ATI, InSilicon, SiS, ...) are anticipated to work without needing significant changes. Use drivers dated "June 2003" or later. |
An if I understood it correctly they talk about kernel level > 2.4.21-pre7 which should match a lot of development done for 2.5.XXX
So... have you tried the vaniila sources 2.4.22_pre8 (package sys-kernel/vanilla-prepatch-sources) ? perhaps they can make you happy and usb fast...
Cheers
