Thank you for confirming my suspicion. I haven't tried more debugging. Maybe this weekend. My approach is to find the code in linux and figure out how to debug the situation from there. The device in question is https://www.globalsat.com.tw/en/product-282242/USB-GNSS-Receiver-BU-353N5.html. It's a cheap receiver and did the job required. > Maybe somewhere along the line you've exposed the device to an OS > which sent it some magic re-configuration command that's now left it > in a mode which the BSD drivers are not designed to handle. This "problem" happened after the upgrade from 7.7 (working) to 7.8 (not working). Thus far, upgrading to 7.8 on other servers is working great. deimos
