Hmm ... I have seen a UPS with similar issues: it actually needs a power cycle on the USB link before it properly enumerates.

Various folk have been reporting similar problems lately, but nobody's sorted out the root cause. - Dave Using Tomcat but need to do more? Need to support web services, security?
