Hi all! I wrote some days ago speaking about a problem with my new PCI USB
card: I sould thank Alan Stern which replied to me promptly and intelligently.
I've made what he said: so I recompiled my kernel modules with debug turned on,
obtaining the following from dmesg (I don't want to spam, so i report only the
essential parts)

The problem is present on the following pci devices: 02:0a.0, 02:0a.2 and

Now I will report the output of the kernel when i plug in the SanDisk USB flash
device which is the only that works....

And all works with this. Now I will disconnect the flash from the bus:

Now I will connect a mouse... for example, but this happens with any
peripheral different than the USB flash I've connected.
I get the following mewssages:

ehci_hcd 0000:02:0a.2: GetStatus port 2 status 003002 POWER OWNER sig=se0 CSC
Ok: from now the USB bus will be unusable ... and I should restart the
computer to get these ports working again. What should I do? Is this an
hardware or a software problem?
Is the problem that the hub is not able to handle 1.1 devices? E deduce it from
the line:
ehci_hcd 0000:02:0a.2: port 2 low speed --> companion
I hope someone has some ideas, thank to all the people reading this.
P.S.: I'm not subscribed to this list, so someone is pleased to send me
eventual replies. If this is a problem I will subscribe myself to this list.
I'ven't done this for now since I'm subscribed to many mailing lists and so I
don't want to be overloaded...
