Hi all,
My M$ keyboard has an integrated usb hub.
whatever usb device is attached to it, when I do a lsusb -v using kernel
2.6test9,8,7,6?, the devices vanish and any subsequent lsusb fails to show
the hub completly.
after removing and reloading uhci-hcd, it works again.
Also, when repluging device from this hub to an other connection, lsusb will
show them twice, as if they still are connected to the keyboard hub. This
strange behaviour does not prevent them from working though.
this did not happen using kernel 2.4.22
This is a partial output of lsusb for (what I beleive to be) the offending
device :
see link below for the other complete lsusb output.

I collected more output @ http://terkuile.xs4all.nl/oops/, including a kernel
segmentation violation when using 2.6-test8 with a usb key which vanished
while mounted. This did not happen with 2.6-test9
note: link above points to my own pc, which is in my bedroom, so is switched
off a night (time is gmt +1).
I don't read the usb list, and the hotmail account displayed above, although
genuine, is my spam address.
So please if you have more questions, need a scan, or just want to thank me
graciouly ;o) :

Thanks,
Ernest.
