USB 2.0 devices not registering
Hi, this is my problem:

I've got an HP Pavilion zv5340us which is "supposedly" equiped with 3 USB 2.0 ports (information from thier site). When I start Linux, I have ehci-hcd, ohci-hcd and uhci-hcd being loaded by my autoload.d (I'm on Gentoo 64bit). When it's loading the ohci-hcd, it always takes a LONG time (ok, not so long, but close to 30secs is too much!). I checked dmesg and there are no errors in the output 9as far as I can tell) except:

Code:

PCI: cache line size of 64 is not supported by device 0000:00:02.2

Intersting facts:
- ehci-hcd recognizes 6 ports; I have 3 and a card-reader
- my USB thumb drive CAN use ehci-hcd
- my Logitech G5 CANNOT use ehci-hcd; it uses ohci-hcd
- Windows tells me that I have NO USB 2.0 ports! (driver problem?)
- there is no option in the BIOS for my USB stuff and I WILL NOT update my BIOS cause last time it killed my computer! and I can't afford to lose the month it would take to get it fixed!
Any ideas? The computer doesn't "recognize" the thumb drive until usb-storage tells it to. I don't see any devfs messages in the dmesg either, so I don't think that that could be it...

Thanks for your help!

What happens if you disable UHCI?

If it isn't even seeing the ports in Windows then I would contact the Vendor and see what they have to say.

uhci-hcd unloading makes no difference in performance, as far as I can tell. It's unloaded now, so... Everything's working fine. The USB thumb drive works with just the ehci-hcd loaded. It's the mouse that won't work...

I could contact the vendor. I flashed the BIOS, unsuccessfully (what a horror when the computer "dies" in front of you but is still "on"!!!), before and it was sent in for repair. I think that this problem showed up after that. I'm not sure. But I don't think they replaced anything, at least nothing was marked as having been replaced... I also have usbhid loaded- does that make any difference?

the Windows I installed was not the Windows that came with the machine (I needed XPPro for school), so I really don't know. In fact, I think it has more to do with the Windows I installed than the computer itself, but seeing as how the mouse is not behaving correctly...

Thanks again!

yeah, usbhid is your mouse.
What do you get if you

cat /dev/input/mice

and then move your mouse around?

Okay, so what's thr problem? Your usb drive works, your mouse works...why are we here?

ok, first, I wanted to say that I did find the driver I needed for Windows and now it works (in Windows). I don't know why it didn't work before, but there you have it.

Secondly, why are we here? Because I would like my mouse to use the USB 2.0 capabilities that it has. I didn't pay $90 for nothing: it's a laser mouse and, if I am not mistaken, the amount of information it sends to the computer on it's highest resolution setting is a lot 9I couldn't say how much but it does 2000dpi ( or more??)). I dunno, if something is made for USB 2, isn't it better to have it working with USB 2 instead of 1.1? It DOES work, yes, but if it can work better, I would like to try and enable the USB 2 for the mouse...

Thanks again for the help!

PS- is there some reason that USBView shows the mouse in red, while it shows the thumb drive (using ehci-hcd) in black?

It always worked it just didn't work how it's supposed to... When the bandwidth is more than 40x smaller than it should be, I think that there is room for improvement, don't you?
