[Tfug] USB bugaboo on Thinkpads

[Jeremy D Rogers]

Ya, that's really good to be aware of. I have done that countless
times on my t60, and no problems yet. Maybe I've been lucky.

Do you happen to have a link or anything from lenovo? I just did a
quick search and didn't see anything. It'd be great to know exactly
what models are at risk.
