USB2.0-Unterstützung

[The Torso]

Ich hab mal ne Frage: auf meinem notebook sind zwei USB 2.0er drauf.
Installiert hab ich momentan den kernel 2.4.18-686 (der beim herunterfahren nicht abschaltet ) und betreibe meine USB-Maus mit "murasaki" (HotPlug Agent).
USB 2.0 wird soviel ich weiß nicht vom Kernel 2.4.18 unterstützt, ab wann aber dann?

Wenn ich lspci abrufe zeigt er mir folgendes auf:

Code: Alles auswählen

00:03.0 USB Controller: Silicon Integrated System [SiS] 7001 (rev 0f)
00:03.1 USB Controller: Silicon Integrated System [SiS] 7001 (rev 0f)
00:03.2 USB Controller: Silicon Integrated System [SiS] 7001 (rev 0f)
00:03.3 USB Controller: Silicon Integrated System [SiS]: Unknown device 7002

Wieso sind bei mir 4 USB angezeigt und der letzte wird nicht erkannt? Habt ihr da eine Ahnung.

Bin eigentlich unterwegs zum Kernel 2.4.21, wenn dort aber auch nicht USB 2.0 unterstütz wird, lohnt sich dann überhaupt der neue Kernel?

Linux Status

People have been using USB 2.0 with usb-storage devices from Linux hosts since June 2001. But it was only towards the end of that year, a short while before Linus created the 2.5 development branch, that other USB 2.0 devices (notably, hubs) began to be available. So while some changes for USB 2.0 were rolling into 2.4 kernels through the year 2001, largely done by about 2.4.10, the most tricky stuff (the ehci-hcd driver) stayed separate until the 2.5 kernel branched. All current Linux distributions include EHCI support, and the end-user bug reports have been helping to stabilize that driver.
Host Controller Driver Support

At this writing the "ehci-hcd" driver is not as well proven as the OHCI or UHCI drivers, so it's still labeled experimental, but it's just fine for many purposes.

* The Linux 2.5 kernel has the most up-to-date USB 2.0 support, as well as quite a number of other USB updates and cleanups.
* The 2.4.19 kernel was the first to bundle a 2.4 based version of the ehci-hcd driver. Expect any 2.4 version to be less current than the 2.5 version, although starting in 2.4.21-pre7 divergence should be much less (with the same patches applying to both kernels, in most cases).
* Older Linux distributions include a 2.4.18 based version that's much like the original 2.5 patch, though more recent distributions (including RedHat 9) match a good 2.4.21-pre level.

Was das mit dem Ausschalten betrifft: Ist das apm bzw. die acpi Modul(e) geladen?
