ohci startup problem

tsy · 09-04-2003, 09:53 AM

Hello everybody,

I already posted this question in the software forum (unfortunately without answer), but perhaps it is better fitting to this forum!?

I installed Mandrake 9.2beta2 on my JVC-XP7250 Laptop (USB 2.0 ports)

When I boot linux with an USB-MemoryStick attached, ohci and ehci load correctly and the MemoryStick can be accessed.
But when I boot with nothing attached to the USB-Ports ohci couldn't be loaded correctly (insmod error), whereas ehci is still loading.

The notebook has a wireless lan adapter which is internally connected to an USB 2.0 port, perhaps this one is causing the problem? Or should the external two USB 2.0 ports work independent of the recognition of the wireless lan adapter?

Greetings,

Thorsten

The outside ports should be a different set than internal. Correct me if wrong but you usually have maximum two ports per controller channel. Are you sure the inside ports are 2.0, the one the lan card is using could be 1.* . At this time I would not know why the module would fail without a memory card or device attached. I could see problems if devices attached.

Something you could try is unplug the lan card and see what happens.

Look at one of my early post on USB. these might help. Not familiar with Mandrake.

As far as I know the NEC USB 2.0 controller is a three port controller. I haven't fully understood how the modules interact with the controller, but it seems you have to be running ohci as well as ehci.

Unplugging the lan card might be not to easy, because they are hardwired within the notebook, which I am not willing to open since it is new and I might loose the guarantee.

I looked a bit around to find some information to solve the problem, but as you are writing normally you get problems when a device is connected when booting and not the other way round.

Thank you for the links, I'll give them a closer look during weekend and perhaps I should give kernel 2.6.0 a try!?

Thank you,

Thorsten
