Once I gave my user account rw access, the scope was found and now responds. I did find confusing the fact that there appear to be two separate sets of these devices, one in /dev and the other in /dev/usb. If I can believe the disparate permissions they are two separate sets, but may be linked in some way I do not understand. IAC, the ones in /dev are the ones I specified in the setup. I also found that the convenient USB hub on top of the PC cabinet, while it worked with the converter and scope under WinXP, did not work with them under FC2, although I routinely use it with Lexar Jumpdrives and the like. I moved the converter to a port on the main board, where it works as advertised. Thanks for your feedback. Chuck
