USB and Wireless problem in Kubuntu fresh install

On thanksgiving, my daughter and I met up, and at her behest (she wanted compiz) I installed Kubuntu 7.10 on her new Lenovo laptop (I think it is an R65) as a dual-boot with WinXP.

The installation initially offered to wipe out the XP installation, but I was a bit more clever than that, and was able to get it to resize a partition then use the free space for the install. I found the path to this procedure to be less obvious than it should have been; only sophisticated computers users are likely to get it right, which would explain a lot of the questions we see here (that is a criticism, btw).

Once done, however, the system dual booted without incident.

To my surprise (and pleasure), wireless immediately was detected and worked. For awhile anyway. Then wireless was crashing. A bit of fiddling established for me that when this happened, shutting down then restarting knetworkmanager would restore the wireless. This is not desirable, obviously. Does anyone know here what might be causing that, and is there a solution?

More seriously, it would appear that periodically the USB bus is crashing, meaning that nothing connected to USB is detected. For her this is indeed a serious problem and might wind up being a showstopper. I didn't have time to fiddle with it and now I am in Arizona and she is in North Carolina, but she signed up here and we might be hearing from her.

In any case, Ol' Dad is expecting a phone call complaining about USB. Does anyone here know what this problem is about?

USB works after booting, and for some time after that. Eventually, due to conditions that have not been pinned down, USB stops working all together. The drivers are installed and apparently still loaded, but the usbdevfs has no entry (which should be named devices) in /proc/usb/. In /var/log/messages are complaints about usbdevfs not being loaded, or not found, or some such (didn't get that all tracked down).

Any suggestions on how to proceed?

It's an R61. And Bluetooth is crashing now too.
