I am an IT engineer with 30-years of experience.I purchased the TrendNET TU-S9 from Amazon.I am running win 7 32-bit on a brand new HP Elite Book 8440pI have updated the driver from the latest one provided on the TrendNet site.After 3-5 minutes of use this adapter blue screens my PC. I have not had any problems prior or since, however every single time I utilize the TU-S9 within 3-5 minutes my laptop Blue Screens.DO NOT PURCHASE THIS PRODUCT if you plan on using it on the latest (with patches) version of Windows 7.
