[Bug 88746] Re: ehci_hcd module causes I/O errors in USB 2.0 devices

BTW, aforementioned output for lspci and lsusb is for the SB600 (laptop)
based system. No USB flash media was attached. I've included the output
for 'lsusb -v' once again, only now with the (Kingston) USB media
attached. I can't reach the other (nforce based) system at the moment,
but...

... the 'No power switching' as well as the '0 milli Ampere' on every
hub has got me frightened.

Maybe the devices are underpowered? I'm logged into other systems (MSI
motherboard, HP Proliant) which show:

Per-port power switching
bHubContrCurrent    100 milli Ampere

I'll try it on the MSI (K9A2 CF motherboard iirc) later on.
